[InstallAPI] Verify that declarations in headers map to exports found in dylib (#85348) 
* This completes support for verifying every declaration found in a
header is discovered in the dylib. Diagnostics are reported for each
class for differences that are representable in TBD files.

* This patch also now captures unavailable attributes that depend on
target triples. This is needed for proper tbd file generation.
