1. Unify WMMA and FPU operator typevars [NFC] …

   The WMMA operator only had a T typevar for the accumulator type,
   while the FPU operator had DT for the destination type and CT for
   the compute type. Unify that by adding both compute type (CT) and
   accumulator type (AT) typevars that indicate the type that should
   be used for the register-level storage and operations.
   
   Note that the WMMA operator's typevars are actually not useful, and
   should match the eltype of the shared memory (as we use WMMA intrinsics
   to load/store shared memory, so cannot convert between shared memory and
   registers). However, we need the accumulator typevar as it cannot be
   inferred from arguments at some points, so I decided to add the compute
   typevar too for alignment with the FPU operator.
