e29ac9bc - [Clang] Do not mark ambiguous specialization invalid. (#147275)

[Clang] Do not mark ambiguous specialization invalid. (#147275) When a specialization was ambiguous, we would mark it as invalid, even if the specialization occured in an immediate context. This would subsequently lead to scenarios where invalid specialization produced no diagnostics, causing crashes during codegen. Fixes #51866
