Previously the input flags were being generated as a reference to an enum member for better readability and under the assumption that minifiers would inline the values. That doesn't appear to be the case so these changes switch to using the literal values instead.

This commit ensures that the new APIs like `input`, `model`, `output`,
or signal-based queries are not accidentally used on fields that have a
problematic visibility/access level that won't work.
For example, queries defined using a private identifier (e.g. `#bla`)
will not be accessible by the Angular runtime and therefore _dont_ work.
This commit ensures:
- `input` is only declared via public and protected fields.
- `output` is only declared via public and protected fields.
- `model` is only declared via public and protected fields.
- signal queries are only declared via public, protected and TS private
fields (`private` works, while `#bla` does not).
Fixes#54863.
