#375
#380

Additional context

Tests:
https://github.com/Dimava/antfu-eslint-config/tree/repro/380-works-fine - uses filesTypeAware: ['src/index.ts'], no errors
https://github.com/Dimava/antfu-eslint-config/tree/repro/380-errors-as-expected - doesn't use filesTypeAware, errors with "not in TS project" on many files

[Dimava]

Seem to be working
Lint crashes because type-aware rules were not used before, as expected - after experimental commit
Lint does not warn of files missing in tsconfig, as expected
If the "typeAwareFiles" is commented out, lint does error that files are missing in tsconfig, as expected
