Implement fine-grained `-Werror=...` facility
This patch add new options `-Werror=...`, `-Wwarn=...` and
`-Wno-error=...` (synonym for `-Wwarn=...`).
Semantics:
- `-Werror` marks all warnings as fatal, including those that don't
have a warning flag, and CPP warnings.
- `-Werror=...` enables a warning and marks it as fatal
- `-Wwarn=...` marks a warning as non-fatal, but doesn't disable it
Test Plan: validate
