This is based on some internal feedback. Adds logic to the standalone migration that attempts to preserve trailing commas when updating existing AST nodes. When creating new ones, it tries to infer whether to generate the trailing comma based on the surrounding code.

These ticks appear in the actual documentation and when copied verbatim while following the tutorial, running this command in the terminal simply does nothing.

This commit increases the threshold of payload size tracking tests from
500 bytes to 5,000 bytes, and from 1% to 5%. This is done to minimize merge
conflicts while still catching real regressions.

Excludes draft PRs from triage queue. Note that we cannot use
`draft:false` as otherwise all issues would be filtered. Rather
we need to negate `draft:true` which matches non-draft PRs and
normal issues.

Showing a minimum app to reproduce the bug.
1. Create the app and add angular material.
```
ng new project
cd project
ng add @angular/material
```
1. Overwrite the src/app/app.component.html with minimal content.
```
<button mat-button *ngIf="true"><span *ngIf="true" class="{{'a'}}"></span></button>
```
1. Run the app. The button is not shown because of an exception.

Because isCssClassMatching() function does not take care if the value is not string, while attrs[] may contain AttributeMarker which is actually numbers, item.toLowerCase() throws the exception.
Just inserted a check if the item is string.
Created a testcase for the original fix. It causes an exception without the fix.
fix(core): add a check code to avoid an exception inside isCssClassMatching

When having a recursive circle of imports on standalone components, `queueTypesFromModulesArrayRecur` triggered a `Maximum call stack size exceeded` error.
This commit fixes this.
Fixes#49469
PR Close#49473
The below error is displayed during some tests
```js
ERROR: 'Unhandled Promise rejection:', 'Cannot read properties of null (reading 'markForCheck')', '; Zone:', 'ProxyZone', '; Task:', 'Promise.then', '; Value:', TypeError: Cannot read properties of null (reading 'markForCheck')
TypeError: Cannot read properties of null (reading 'markForCheck')

```
This is caused by the fact that `ref` in `AsyncPipe` is initialized with a value of `null` which causes `_updateLatestValue` to fail since it is not expected to be `null`.
This change ensures that a `ref` is always provided and that all subscriptions are disposed off after each test.

Before this change `ɵɵdefineDirective` called `ɵɵdefineComponent` under the hood. This is problematic for the consistent component id generation as it could result in hash collisions for certain directives. Directives however do not require an id.
This changes moves common definition generation logic into a separate function that is re-used in `ɵɵdefineDirective` and `ɵɵdefineComponent`.

The decorator downlevel transform is never used for actual class
decorators because Angular class decorators rely on immediate execution
for JIT. Initially we also supported downleveling of class decorators
for View Engine library output, but libraries are shipped using partial
compilation output and are not using this transform anymore.
The transform is exclusively used for JIT processing, commonly for
test files to help ease temporal dead-zone/forward-ref issues. We can
remove the class decorator downlevel logic to remove technical debt.
