* 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
