When using the legacy digest algorithm for i18n messages, the output hexadecimal
string now leverages a number's `toString()` function in addition to the `padStart`
string function to generate the result. This removes the need for several helper
functions which involved a series of iteration and bitwise operations to previously
generate the same output.

The native UTF-8 encoder (`TextEncoder`) provides its output as a `Uint8Array`
which is a specialized `TypedArray` for storing byte values. To remove the need
to copy and transform this data multiple times, a `DataView` is used to allow
for low-level access to the data in a variety of bit-widths and endianness.
The `DataView` class is natively available and supported by all browsers and
Node.js versions support by the framework (https://caniuse.com/mdn-javascript_builtins_dataview).
PR Close#48256
Instead of relying on a custom implementation of a UTF-8 text encoder that needs to
be maintained by the Angular team, the i18n message digesting process now uses the
native `TextEncoder` class. This class is available for use in all browsers and Node.js
versions supported by the Angular framework (https://caniuse.com/textencoder). The
custom encoder is still used by the compiler's source map generator and cannot yet be
fully removed.

Because the language service uses the compiler, we try to produce as
much useful information as possible rather than throwing hard errors.
Hard errors cause the compiler to crash. While this can be acceptable
when compiling a program as part of a regular build, this is undesirable
for the language service.

This commit removes the unnecessary `assignExtraOptionsToRouter` helper
function. This helper is not necessary because the options can be
retrieved from DI and assigned during the construction on the Router.

The Router constructor and `setupRouter` factory mainly exist as a
legacy configuration. Since the Router's creation, the style in Angular
has evolved quite a bit. This commit eliminates and cleans up some
unnecessary comlicated code paths related to the router
constructor/factory.
Note that there are edits to the `setupTestingRouter` that could be seen
as breaking. However, it is not for several reasons:
1. The function is documented as a factory function. If used as
documented, the parameters should match what's available in DI
2. The function is totally unused by the Router itself and is not used
in g3 either. I believe it was made publicApi by an error when
updating documentation annotations long ago.

This commit removes several debug data structures from
the framework runtime. The data structures in question
were introduced in the framework in the past with the
idea of having debugging aid in the form of the human-redable
data structures. It turned out that in practice those
data structures were not used (most of the fwk developers
didn't even know about their existence!), yet we kept
paying the price of maintaining those duplicated (prod
and debug) version of the data structures.

This option has already been removed from availability externally. Internally, the last use has been removed
for the type on Route.loadChildren. More testing will be necessary to verify nothing relies on the other
code paths.

processed through the navigation pipeline. This tracking should be
done as part of the navigation transition handler

Rather than accessing router internal properties that are available in DI,
this commit directly injects those dependencies in the navigation transition
handler. Note that there are several other items that _should_ be injectable
in DI (like the TitleStrategy) but because those are part of the Router public
interface and writeable(!), they might be changed during runtime. We
have to get these other items from the Router for now...

As mentioned in #46021, `canMatch` guards can replace `canLoad`. There
are slight differences between the two but the purpose of preventing
user access to feature modules is still achievable. There are several
reasons keeping `CanLoad` around is detrimental to the API surface:
* Lazy loading should not be an architectural feature of an application. It's an
optimization you do for code size. That is, there should not be an architectural
feature in the router to directly specifically control whether to lazy load something or
not based on conditions such as authentication. This slightly
different from the `canMatch` guard: the guard controls whether
you can use the route at all and as a side-effect, whether we download the code.
`CanLoad` only specified whether the code should be downloaded so `canMatch` is
more powerful and more appropriate.
* The naming of `CanLoad` will be potentially misunderstood for the `loadComponent` feature.
Because it applies to `loadChildren`, it feels reasonable to think that it will
also apply to `loadComponent`. This isn’t the case: since we don't need
to load the component until right before activation, we defer the
loading until all guards/resolvers have run.
* Unnecessary API surface bloat where two features (CanMatch and CanLoad) do
essentially the same thing. This affects code size for supporting two
nearly identical features as well as the learning and teaching journey
for them both.
* `CanLoad` guards have the downside of _only_ being run once to prevent
loading child routes. Once that passes and children are loaded, the
guard never runs again. As a result, developers need to always provide
_both_ canLoad and a canActivate in case the answer to the guard flips
back to `false`. This is not the case for `canMatch`, which will run
on every navigation.
DEPRECATED: CanLoad guards in the Router are deprecated. Use CanMatch
instead.

The stricter checks under `strictInjectionParameters` in Angular 15 now enforce that
an inherited constructor must be compatible with DI, based on whether all parameters
are valid injection tokens. There is an issue when the constructor is inherited from
a class in a declaration file though, as information on the usage of `@Inject()` is
not present within a declaration file. This means that this stricter check cannot be
accurately performed, resulting in false positives.
This commit disables the stricter check to behave the same as it did prior to
Angular 15, therefore avoiding the false positive.
