When there was more than one rule in a single style string, only the first
rule was having its `:host` selector processed correctly. Now subsequent
rules will also be processed accurately.

Previously presence of both [class] and [className] bindings on an element was treated as compiler error (implemented in https://github.com/angular/angular/commit/6f203c9575fe9a2da04529fbdf1e5f7b51e85e09). Later, the situation was improved to actually allow both bindings to co-exist (see https://github.com/angular/angular/commit/a153b610983389de6408f7a723fd5714a11c168e), however the compiler check was not removed completely. The only situation where the error is thrown at this moment is when static (but with interpolation) and bound `class` attributes are present on an element, for ex.:
```
<div class="{{ one }}" [class]="'two'"></div>
```
In the current situation the error is acually misleading (as it refers to `[className]`).
This commit removes the mentioned compiler check as obsolete and makes the `class` and `style` attribute processing logically the same (the last occurrence is used to compute the value).

This commit fixes the behavior when creating a type constructor for a directive when the following
conditions are met.
1. The directive has bound generic parameters.
2. Inlining is not available. (This happens for language service compiles).
Previously, we would throw an error saying 'Inlining is not supported in this environment.' The
compiler would stop type checking, and the developer could lose out on getting errors after the
compiler gives up.
This commit adds a useInlineTypeConstructors to the type check config. When set to false, we use
`any` type for bound generic parameters to avoid crashing. When set to true, we inline the type
constructor when inlining is required.

The recently introduced typings-only mode in ngcc would incorrectly
write compiled JavaScript files if typings-only mode was requested, in
case the typings of the entry-point had already been processed in a
prior run of ngcc. The corresponding format property for which the
JavaScript files were written were not marked as processed, though, as
the typings-only mode excluded the format property itself from being
marked as processed. Consequently, subsequent runs of ngcc would not
consider the entry-point to have been processed and recompile the
JavaScript bundle once more, resulting in duplicate ngcc imports.

Currently the `Validators` class contains a number of static methods that represent different validators as well as some helper methods. Since class methods are not tree-shakable, any reference to the `Validator` class retains all of its methods (even if you've used just one).
This commit refactors the code to extract the logic into standalone functions and use these functions in the code instead of referencing them via `Validators` class. That should make the code more tree-shakable. The `Validators` class still retains its structure and calls these standalone methods internally to keep this change backwards-compatible.

Previously, we used the `hotlist: community-help` label to mark issues
that were good candidates for contributions from the community.
Recently, we also started using the `good first issue` label to mark
issues that would additionally be suitable for first-time contributors.
This commit is part of the work to replace `hotlist: community-help`
with the newly added `help wanted` label, which (same as
`good first issue`) is a [default GitHub label][1]. This commit changes

Before #41162, angular.io was broken on IE 11 due to missing a polyfill
for an API (`Reflect.construct()`) needed by the Custom Elements ES5
shim. #41162 tried to fix this by loading the necessary polyfill
(`es.reflect.construct.js`) on browsers that do not support ES2015
modules (including IE 11).
It turns out that the fix in #41162 was itself broken, because the
`es.reflect.consruct.js` script (included directly in the page via a
`<script>` tag) was in CommonJS format (which cannot run in the browser
as is). By chance, this still allowed browsers that supported neither
Custom Elements nor ES2015 modules (such as IE 11) to work correctly as
a side-effect of loading the `@webcomponents/custom-elements` polyfill
after the Custom Elements ES5 shim (`native-shim.js`). However, on the
few browsers that natively support Custom Elements but not ES2015
modules, angular.io would still be broken.
This commit correctly fixes angular.io on all browsers by properly
bundling the polyfills and transpiling to ES5.
Implementation-wise, we use [esbuild][1] for bundling the polyfills (and
converting from CommonJS to a browser-compatible, IIFE-based format) and
[swc][2] for downleveling the code to ES5 (since `esbuild` only supports
ES2015+).

Previously, the angular.io app was broken on IE 11. In particular, pages
that included Custom Elements would fail to load, because the
`Reflect.construct()` method (which the Custom Elements ES5 shim relies
on) was not available.
This commit fixes this by loading the polyfill for `Reflect.construct()`
on browsers that do not support ES2015 (including IE 11).

The custom elements spec is not compatible with ES5 style classes. This
means ES2015 code compiled to ES5 will not work with a native
implementation of Custom Elements. To support browsers that natively
support Custom Elements but not ES2015 modules, we load
`@webcomponents/custom-elements/src/native-shim.js`, which minimally
augments the native implementation to be compatible with ES5 code.
(See [here][1] for more details.)
Previously, the shim was included in `polyfills.ts`, which meant it was
loaded in all browsers (even those supporting ES2015 modules and thus
not needing the shim).
This commit moves the shim from `polyfills.ts` to a `nomodule` script
tag in `index.html`. This will ensure that it is only loaded in browsers
that do not support ES2015 modules and thus do not needed the shim.
NOTE:
This commit also reduces size of the polyfills bundle by ~400B
(52609B --> 52215B).

When there are elements in a translated message, the start and end tags
are encoded as placeholders. The names of these placeholders are computed
from the name of the element. For example `<a> will be `START_LINK` and
`</a>` will be `CLOSE_LINK`.
If there are more than one element with the same name, but different attributes,
then the starting placeholder name is made unique.
For example `<a href="a">` would be `START_LINK`, while `<a href="b">` in
the same message would then be called `START_LINK_1`.
But the closing tags will not be made unique since there are no attrbutes;
the always have the same text `</a>`, which will produce, for example,
`CLOSE_LINK`.
Previously, when extracting XLIFF 2 formatted translation files, the closing
tag placeholder names were computed incorrectly from the opening tag
placeholder names. For example `CLOSE_LINK_1`.
This commit strips these `_1` type endings from the start tag placeholder
name when computing the closing tag placeholder name. It also ensures
that the `type` of the placeholder is computed accurately in these cases
too.

The Angular compiler creates two `ts.Program`s; one for emit and one for
template type-checking. The creation of the type-check program could
benefit from reusing the `ts.ModuleResolutionCache` that was primed
during the creation of the emit program. This requires that the compiler
host implements `resolveModuleNames`, as otherwise TypeScript will setup
a `ts.ModuleResolutionHost` of its own for both programs.
This commit ensures that `resolveModuleNames` is always implemented,
even if the originally provided compiler host does not. This is
beneficial for the `ngc` binary.

characters).
