  [AMDGPU] Use 32-bit index for SWMMAC builtins

Currently, the index of SWMMAC builtins is of type `short`, likely based on the
assumption that K can only be up to 32, meaning there are only 16 non-zero
elements. However, this is not future-proof. This patch updates all of them to
`int`.

The intrinsics themselves don't need to be updated since they accept any integer
type, and in the backend, they are already extended to 32-bit. Additionally, the
tests already use various kinds of integers.

Partially fixes SWDEV-518183.
