[Clang][TableGen] Add explicit symbol visibility macros to code generated (#109362)

Browse Source 
Update ClangAttrEmitter TableGen to add explicit symbol visibility
macros to attribute class declarations it creates.
Both AnnotateFunctions and Attribute example plugins require
clang::AnnotateAttr TableGen created functions to be exported from the
Clang shared library.
This depends on macros to be added in
