Add target settings attribute to toolchain rule This is the implementation of proposal https://docs.google.com/document/d/13yXhOQeMZQmlW3obyZ7fJP3sm3eVLbK3Nuk2LZjcZiU/edit. The added `targetSetting` attribute, can reference `config_setting` rules. The attribute is resolved in target configuration and the returned `ConfigMatchingProvider` already has the value if this toolchain matches. Difference to the proposal is that `targetSettings` are a `LABEL_LIST` where all the settings need to be satisfied. This might increase a bit usability. It makes the implementation a bit nicer, because instead of special handling when the value is not present, a list can uniformly handled. Closes #12425. RELNOTES: Toolchain rule is extended with target_settings attribute. PiperOrigin-RevId: 341386320
