util: Use ZSTD for shader cache if possible
This allows ZSTD instead of ZLIB to be used for compressing the shader
cache.
On a 72 core system emulating skl with a full shader-db (with i965):
ZSTD:
1915.10s user 229.27s system 5150% cpu 41.632 total (cold cache)
225.40s user 10.87s system 3810% cpu 6.201 total (warm cache)
154M (235M on disk)
ZLIB:
2231.33s user 194.24s system 1899% cpu 2:07.72 total (cold cache)
229.15s user 10.63s system 3906% cpu 6.139 total (warm cache)
163M (244M on disk)
Tim Arceri sees (8 core ryzen and a full shader-db):
ZSTD:
2505.22 user 40.50 system 3:18.73 elapsed 1280% CPU (cold cache)
418.71 user 14.93 system 0:46.53 elapsed 931% CPU (warm cache)
454.3 MB (681.7 MB on disk)
ZLIB:
3069.83 user 40.02 system 4:20.13 elapsed 1195% CPU (cold cache)
425.50 user 15.17 system 0:46.80 elapsed 941% CPU (warm cache)
