test: migrate form control usages to modern syntax (#28897)

Issue number: Internal

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Several tests were still using the legacy form syntax.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Migrated tests in `core`, `angular`, and `vue` to use the modern form
syntax (`react` did not have form controls).

I opted not to migrate `item/test/highlight` and `item/test/counter`
because those tests are going to be removed in the future once the
deprecate item APIs are removed.
