[clang-tidy] performance-* checks: Match AllowedTypes against qualified type...

[clang-tidy] performance-* checks: Match AllowedTypes against qualified type names when they contain "::".

This allows users to be more precise and exclude a type in a specific namespace
from triggering the check instead of excluding all types with the same
unqualified name.

This change should not interfere with correctly configured clang-tidy setups
since an AllowedType with "::" would never match.
