Eliminate FLUTTER_NOLINT where possible (#21904) 
This removes most of the remaining FLUTTER_NOLINT comments and opts
these files back into linter enforcement.

I've filed https://github.com/flutter/flutter/issues/68273 to require
that all FLUTTER_NOLINT comments be followed by a GitHub issue URL
describing the problem to be fixed.
