LOG: [Clang][ASTMatchers] Add visibility macros to variables declared by macros (#110206)

This will fix missing symbols for ASTMatchersTests on windows when
building with CLANG_LINK_CLANG and explicit visibility macros are used.
This PR depends on macros that will be be added in #108276
This is part of the work to enable LLVM_BUILD_LLVM_DYLIB and LLVM\Clang
plugins on window.
