  [Clang][RISCV] Recognize unsupport target feature by supporting isValidFeatureName (#106495)

This patch makes unsupported target attributes emit a warning and ignore
the target attribute during semantic checks. The changes include:

1. Adding the RISCVTargetInfo::isValidFeatureName function.
2. Rejecting non-full-arch strings in the handleFullArchString function.
3. Adding test cases to demonstrate the warning behavior.
