I'm pretty sure that I did not find every thing that needs to be ported. At least the addon is usable again.
I replaced deprecated icons with NONE. Someone else, who is responsible for this addon, can choose some new icons.

Bumped version to 1.1.5
Pep8 cleanup
Remove the pie_origin_cursor.py since it is not needed anymore
Part of the T51547:
refactor the key unregister code so it matches the official pies
Note: using this code was crashing blender because of Bool Tool
key registration that left out some lingering keys on unregister
reload
Also there were some wrong calls with the unregister within the
pies themselves
Merge some operators where possible (around 7 less in total)
and use passing arguments instead
Add Enable All / Disable all buttons in the preferences
Comment out the code for authors in the init instead of in
individual scripts
Remove unused imports and cameratoto scene prop
Add an icon at end of registrations line
Fix several crashes with operators being called out of context
