  [clang] callee_type metadata for indirect calls (#163233)

Create and add generalized type identifier metadata to indirect calls,
and to functions which are potential indirect call targets.

The functions carry the !type metadata. The indirect callsites carry a
list of !type metadata values under !callee_type metadata.
