[gdb/tdep] Use raw_supply_part_zeroed for AArch64
In gdb/aarch64-linux-tdep.c we find:
...
gdb::byte_vector za_zeroed (za_bytes, 0);
regcache->raw_supply (tdep->sme_za_regnum, za_zeroed);
...
We can't use reg_buffer::raw_supply_zeroed here because only part of the
register is written.
Add raw_supply_part_zeroed, and use it instead.
Likewise elsewhere in AArch64 tdep code.
Tested on aarch64-linux.
