[CIR] Upstream support for name mangling (#137094)

We have been using the default names for global symbols to this point.
This change introduces proper name mangling for functions.

This requires introducing a CXXABI class in the CIRGenModule. Because
only target independent name mangling is handled in this patch, the
CXXABI class does not require a target-specific implementation. The
general mechanism for selecting an implementation is introduced here,
but the actual target-specific subclasses are deferred until needed.
