  [C23] AST equivalence of attributes (#151196)

Implicitly declared types (like __NSConstantString_tag, etc) will be
declared with visibility attributes. This causes problems when merging
ASTs because we currently reject declaration merging for declarations
with attributes.

This relaxes that restriction somewhat; implicit declarations can now
have attributes when merging; we assume that if the compiler generated
it, it's fine.
