Adds a function that allows for the import resolution for files to be customized in the standalone migration. Externally it's only use is to change `NgForOf` to `NgFor`, but we'll need it internally to deduplicate some Material modules.

`setDisabledState` is supposed to be called whenever the disabled state of a control changes, including upon control creation. However, a longstanding bug caused the method to not fire when an *enabled* control was attached. This bug was fixed in v15.
This had a side effect: previously, it was possible to instantiate a reactive form control with `[attr.disabled]=true`, even though the the corresponding control was enabled in the model. (Note that the similar-looking property binding version `[disabled]=true` was always rejected, though.) This resulted in a mismatch between the model and the DOM. Now, because `setDisabledState` is always called, the value in the DOM will be immediately overwritten with the "correct" enabled value.
Users should instead disable the control directly in their model. (There are many ways to do this, such as using the `{value: 'foo', disabled: true}` constructor format, or immediately calling `FooControl.disable()` in `ngOnInit`.)
If this incompatibility is too breaking, you may also opt out using `FormsModule.withConfig` or `ReactiveFormsModule.withConfig` at the time you import it, via the `callSetDisabledState` option.
However, there is an exceptional case: radio buttons. Because Reactive Forms models the entire group of radio buttons as a single `FormControl`, there is no way to control the disabled state for individual radios, so they can no longer be configured as disabled.
In this PR, we have special cased radio buttons to ignore their first call to `setDisabledState` when in `callSetDisabledState: 'always'` mode. This preserves the old behavior.

Fixes that the migration was unnecessarily traversing top-level nodes. This was a large performance bottle-neck, because it involves a lot of language service lookups.
PR Close#49010
In some internal migrations the language service was throwing for some file reads which was crashing the migration. These changes add a `try/catch` to avoid interrupting it.
PR Close#49010
For the module pruning and bootstrap API migration steps we depend heavily upon the TypeScript `LanguageService` which ends up being slow on a large project. E.g. in some large internal projects single-file lookups were taking around 30s.
These changes introduce a wrapper around the `LanguageService` that we can use to trick it into not traversing the entire project every time.

Normally having a standalone declaration in the `imports` array is an error and something we handle in the conversion to standalone, but tests can end up in this situation, because apps may have separate tsconfigs for the main app and for tests.
These changes make it so that we move any incorrectly-defined standalone declarations, even if they aren't part of the current migration.

The first step of the migration updates the tests of the component being migrated, however it also skips any bootstraped declarations. We get back to the these declarations when converting to the standalone bootstrapping APIs, but we weren't updating their tests.
These changes rework some of the logic so that we migrate any remaining tests as a part of the final step.
Relates to #48944.

Currently the standalone migration is set up to skip any modules that have a `bootstrap` array with at least one element. This ends up being misleading for small apps who have everything in the root module.
These changes add some logic to only skip the root component.

v16 will have a breaking change to the way `UrlTree`s are constructed.
This change is actually a bug fix that makes `UrlTree` creation correct
in more scenarios (see #48508). However, this can affect applications that are
relying on the current incorrect behavior. This commit adds a dev mode
warning when the target of a navigation will change once #48508 is
submitted.

In #48898 the `isForwardRef` flag was added to indicate whether a reference should be wrapped in a `forwardRef`. This logic assumed that the node can't be referring to another node within the same file, however from testing it looks like that's not actually the case, because we hit the same code path when an external import to the same symbol exists already.

Fixed a typo and updated the hyphenation in a couple of words to keep consistency across schematics docs style. Assuming beginners reading docs, I also added the property called
public showGreeting = true;
This is because it is available in the examples `.HTML` `*ngIf` directive snippets without being present in the `.ts` class properties declarations. also this removes potential inference that this absence is a result of the standalone migration schematics work.

In the `PotentialImport` we indicate if it's in the same file by not setting a `moduleSpecifier`, but if that's the case, the imported symbol might need to be wrapped in a `forwardRef` to avoid generating an error. These changes expose this information so the various tools can take advantage of it.
