  Add limited vtable address querying to `clang::CodeGenerator` (#202807)

This is being used in Carbon (
https://github.com/carbon-language/carbon-lang/pull/7323 ) to implement
cross-language overriding.

I realize this isn't the fully general feature needed for virtual bases,
etc - but this limited functionality is already wrapped up for, if I
understand it correctly, constexpr use cases and some others. So
hopefully it's still something folks feel is general enough to be
worthwhile exporting. For now Carbon doesn't support deriving from a
type with virtual bases, so the extra complexity isn't needed.
