[Dwarf] Support heterogeneous DW_{OP,AT}s needed for AMDGPU CFI (#153883) 
These are defined in the user range until standard versions of them get
adopted into dwarf, which is expected in DWARF6.

Some of these amount to reservations currently as no code to use them is
included. It would be very helpful to get them committed to avoid
conflicts necessitating encoding changes while we are in the process of
upstreaming.
