Wire up the Mesa shader disk cache into Panfrost. Coupled with the precompiles from the previous patch, this should greatly reduce shader recompile jank. This is a bare bones implementation. Obvious future work includes: - Caching internal (outside of Gallium) shaders - Implement finalize_nir to reduce on disk size of shaders That doesn't need to come in this patch. This patch does shuffle some allocation patterns around to avoid extra nir_shader_clones, but the result should be pretty clean. --- Consider dEQP-GLES31.functional.ssbo.layout.basic_unsized_array.* in the CTS.
