intel/fs: fix subgroup invocation read bounds checking
nir->info.subgroup_size can be set to an enum :
SUBGROUP_SIZE_VARYING = 0
SUBGROUP_SIZE_UNIFORM = 1
SUBGROUP_SIZE_API_CONSTANT = 2
SUBGROUP_SIZE_FULL_SUBGROUPS = 3
So compute the API subgroup size value and compare it to the dispatch
size to determine whether we need some bound checking.
