[lldb][NFC] Move definition of ClangASTMetadata out of ClangExternalASTSourceCommon.h

Changing metadata of a ClangASTContext currently requires to include
the unrelated ClangExternalASTSourceCommon.h header because it actually defines
the ClangASTMetadata class.

This also removes the dependency from ClangASTImporter to ClangExternalASTSourceCommon.
