cexbrayat 95830ee584 feat(common): stricter types for SlicePipe (#30156)
Adds overloads to the `transform` methods of `SlicePipe`,
to have better types than `any` for `value` and `any` as a return.
With this commit, using `slice` in an `ngFor` still allow to type-check the content of the `ngFor`
with `fullTemplateTypeCheck` enabled in Ivy:

    <div *ngFor="let user of users | slice:0:2">{{ user.typo }}</div>
                                                        |
                                                        `typo` does not exist on type `UserModel`

whereas it is currently not catched (as the return of `slice` is `any`) neither in VE nor in Ivy.

BREAKING CHANGE
`SlicePipe` now only accepts an array of values, a string, null or undefined.
This was already the case in practice, and it still throws at runtime if another type is given.
But it is now a compilation error to try to call it with an unsupported type.
