Add Drilling cycles (G81, G82 and G83)

[FNeo31]

Description

Add Canned Drilling cycles (G81, G82 and G83)
(need to repeat the G code cycle each position no need to cancel for this reason)
Prepare the develop of 5 axis CNC milling (without RTCP for now)

Increase the number of variables for custom menu (from 5 to 20) and custom CNC Users preset variables to easy probing and define Zeros (G54 to G59)

Need to optimizations in some sections

Benefits

Add Canned Drilling cycles (G81, G82 and G83)

Increase the number of variables for custom menu (from 5 to 20)

Related Issues

[FR] Add Drilling canned cycles to Marlin 2.0 #14448
Add G81 and G83 drilling cycles #14225

Great work, I like this idea.
Your pull request would probably get more support if you were not using all the custom menus.
Have you thought of implementing your own CNC menu?
It could be used exactly like CUSTOM_USER_MENUS.
The code below is based off of menu_custom.cpp and should get you started:
