radv: add drirc options to force re-compilation of shaders when needed

Browse Source 
On Steam Deck, shaders are pre-compiled for better performance (less
stuttering, less CPU usage, etc). But when a compiler fix needs to be
backported, there is currently no way to handle this properly.

This introduces 3 drirc options
radv_override_{graphics,compute,ray_tracing}_shader_version in order to
force the driver to re-compile pipelines when needed. By default, the
shader version is 0 for all pipelines.

When one drirc is set for a specific game, RADV will re-compile all
pipelines only once with the compiler fix included (because the
pipeline key would be different).
