v3dv/pipeline_cache: cache v3dv_shader_variants

This also includes being able to serialize them as part of
GetPipelineCacheData and to deserialize it as part of
CreatePipelineCache.

So now we can also upload the assembly of the variant as part of the
PipelineCache creation.

Note that from all this the tricky part was the prog_data
serialization. v3d_compile allocates and fill a new prog_data, with
rzalloc. Among other things because it also allocates internally the
uniform list. So we needed to replicate that when deserializating the
prog_data. Ideally we would like to avoid that, and allocate as much
resources as possible using vk_alloc, but that would mean a somewhat
deep change on the v3d_compiler, that we want to avoid as much
possible for now.
