  [SystemZ] Emit external aliases for indirect function descriptors in the ADA section (#183443)

This is the last of the three patches aimed to support indirect symbol
handling for the SystemZ backend.

An external alias is emitted for indirect function descriptors within
the ADA section, rather than a temporary alias, while also setting all
of the appropriate symbol attributes that are needed for the HLASM
streamer to emit the correct XATTR and ALIAS instructions for the
indirect symbols.

Moreover, this patch updates the
`CodeGen/SystemZ/zos-ada-relocations.ll` test as the ADA section is
currently the only user of indirect symbols on z/OS.

Depends on https://github.com/llvm/llvm-project/pull/183442.
