AArch64: Fix strict-align cpymem/setmem [PR103100]
The cpymemdi/setmemdi implementation doesn't fully support strict
alignment.
Block the expansion if the alignment is less than 16 with STRICT_ALIGNMENT.
Clean up the condition when to use MOPS.

* config/aarch64/aarch64.md (cpymemdi): Remove pattern condition.
(setmemdi): Likewise.
* config/aarch64/aarch64.cc (aarch64_expand_cpymem): Support
strict-align. Cleanup condition for using MOPS.
(aarch64_expand_setmem): Likewise.
