feat(app): better handle multiple types, default values, and options for input/output/model signals

[bameyrick]

Extends the work in #1439 to:

• Allow for options to be provided with a default value input('value', { transform: (value) => value.toLowerCase() })
• Allow for multiple types for inputs e.g. input<string | number>(), input<'button' | 'reset'>()

This doesn't fully address some of the comments in #1439 to use babel, however it should handle more cases for input/output/model signals.

Closes #1498

Hi,
Thank for this PR.
Could you add unit tests for that in test/src/cli/cli-generation-big-app.spec.ts?
🙏🏻

Hi @vogloblinsky, I've added some (admittedly very messy) tests and made sure the signal's default values/types also work with periods and underscores .

@bameyrick great work!

@vogloblinsky I'm not sure whether compodoc has a release schedule.
When do you plan to create a new release?

[vogloblinsky]

I am on it, this week ;)

@vogloblinsky I guess you're busy, any update on the release?

@vogloblinsky Any chance of getting this fix released soon? :)
