Refactor: convert "F-Curve path refactor" code to current Action API

Browse Source 
Convert the code in `scripts/modules/animsys_refactor.py` from the
legacy Actions API to the current API.

The code was made for very old rigs (2.70 and older, last updated for
Caminandes in 2014). The updated code seems to work on a Caminandes test
file, and produces the same logging on the terminal as in Blender 4.3
(before slotted Actions).

No functional changes.

This is part of #146586
