gallium: change PIPE_COMPUTE_CAP_SUBGROUP_SIZE to a bitfield of sizes

Browse Source 
This will be required for `cl_intel_required_subgroup_size`, but it
already helps implementing OpenCL subgroups as this allows us to check
with every subgroup size when implementing
`CL_KERNEL_LOCAL_SIZE_FOR_SUB_GROUP_COUNT`.
