* arm64 python: Avoid nested class in insn hook for 10x hook speedup

Promote CpReg to a module-level class to address unnecessary performance
reduction.  In a real-world use case tracing the emulation of real-world
machine code, this change reduces time spent in CpReg namedtuple
construction from 10% of overall time to below 1%, for a 10x speedup of
the insn hook itself, or a 10% overall speedup.  Measured using
cProfile, python 3.13.

* upgrade distro to 22.04

* revert to 22.04 for now

* also revert for wheels
