[AArch64] Add support for GMID_EL1 register for +memtag
We're missing support for the GMID_EL1 system register from the Memory Tagging Extension in binutils.
This is specified at:
https://developer.arm.com/docs/ddi0595/latest/aarch64-system-registers/gmid_el1
This simple patch adds the support for this read-only register.
Tested make check on gas.
