[AArch64][libopcode] Add support for PAN architecture extension

Browse source 
The ARMv8.1 architecture introduced the Privileged Access Never extension. This
adds a processor state field PSTATE.PAN which can be accessed using the MRS/MSR
instructions.

This patch adds support for the PAN architecture feature and processor state
field to libopcode.
