chore(core): type checking for unit tests (#28529)

Browse Source 
Issue number: N/A

---------

<!-- 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. -->

Type checking inside of the Stencil unit tests have been disabled for a
long time. This has resulted in a difficult developer experience and
numerous issues (both types and implementation) within our unit tests.

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

- Type checking is now enabled for all Stencil unit tests
- Tests have been updated to resolve type errors and implementation
errors
- Many `as any` casts were introduced, as many legacy tests test invalid
configurations of functions that require it (for example passing
`undefined` to an argument that cannot be `undefined`).

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

To test this PR you can checkout the branch locally. Install
dependencies in the `/core` directory to make sure you are on at least
`@stencil/core@4.7.2`.

Opening either a `.spec.ts` or `.spec.tsx` file, validate that your IDE
detects types and can provide auto completions for jest global types.

If you desire, you can provide an invalid type and try building the
project - you will observe the build will fail due to the invalid type.
