Tatsuyuki Ishi 991ae339f5 radv: Implement NIR caching behind RADV_PERFTEST=nircache.
NIR caching is useful for two use cases:
- Shader permutations involving reused VS or FS.
- GPL-like engine that compiles a separate (library) variant and an
  optimized (monolithic) variant, e.g. DXVK.

By caching the result of radv_shader_spirv_to_nir, permutations hitting
the cache can have their compilation time reduced by 50% or more.

There are still open questions about the memory and storage footprint of
NIR caches, which is why this is gated behind a perftest flag. In
particular, Steam doesn't want to ship NIR cache since they are
unnecessary in presence of a full precompiled shader cache. In this
commit, the cache entries do not reside in memory and are immediately
written to the disk. Further design around how the caches are stored and
how to coordinate cache type with Steam etc. is left as future work.
