Glint.fix refactoring to use rehearsal collections of codefixes

[egorio]

Glint service provides a function getDiagnostics which is used by glint.fix plugin. The getDiagnostics function combines TS diagnostics together with glint ones, and does some post-processing. Unfortunately, this prevents us from using rehearsal-provided codefixes and requires duplicating the code from ts-codefixes.

The good part is that glint exposes a transformManager which allows us to reproduce getDiagnostics outside of glint.

This means we can try to implement glint-codefixes-collection to return glint-specific codefixes and consume base-codefixes and ts-codefixes directly from rehearsal source.
