TargetGenerator: Factor out generation of code check rules

De-duplicate code check rule generation in Ninja and Makefile generators
by moving their implementation to `cmCommonTargetGenerator`.

Previously Ninja was generating code check rules per language.
It was changed to generate code check rules for each source file.
