[AArch64] Widen GPR32 zero cycle zeroing (#164244)
Given a GPR32 zeroing instruction, if the target supports zero cycle
zeroing for GPR64 but not for GPR32, widen the instruction to 64 bit
`$xn = MOVZXi 0, 0` instead of writing to `$wn` to exploit zero cycle
zeroing.
It also aligns naming in the generic zeroing test.
