[PATCH i-g-t 09/11] lib/intel_compute: Fix enqueued local size in xehp

According to the metadata of the compute kernel used for this test, the
enqueued_local_size comes at offset 52, right after the value of the
"count" argument. Fix it and add comments for clarity.

Relevant part of the kernel metadata:

      - arg_type:        arg_bypointer
        offset:          32
        size:            8
        arg_index:       0
        addrmode:        stateless
        addrspace:       global
        access_type:     readwrite
      - arg_type:        arg_bypointer
        offset:          40
        size:            8
        arg_index:       1
        addrmode:        stateless
        addrspace:       global
        access_type:     readwrite
      - arg_type:        arg_byvalue
        offset:          48
        size:            4
        arg_index:       2
      - arg_type:        enqueued_local_size
        offset:          52
        size:            12
