[AMDGPU] Skip VGPR deallocation for waveslot limited kernels (llvm#112765)
MSG_DEALLOC_VGPRS slows down very small waveslot limited kernels. It's been identified this message is only really needed for VGPR limited kernels. A kernel becomes VGPR limited if a total number of VGPRs per SIMD / number of used VGPRs is more than a number of wave slots.
