Samuel Pitoiset 4308668a25 radv: allow shaders caching with RADV_DEBUG=hang and the trap handler
When debugging a game that compiles a ton of shaders at beginning, it
can be very very slow because shaders cache was disabled by default
with RADV_DEBUG=hang.

To make debugging such a game faster, let's cache shaders with
RADV_DEBUG=hang. Note that only the backend IR (ACO or LLVM) and the
disassembly are stored in the cache. To get SPIR-V and NIR, you might
need RADV_DEBUG=hang,nocache.

This also handles the trap handler.
