Update most cannonkeys 072 boards to rely on core QMK/VIA support

[awkannan]

Description

My apologies to @zvecr, I know you had a PR out but I wanted to one-fell-swoop my 072 folder away, now that all the functionality is in core QMK.

I have removed my special 072 folder and now rely on the core QMK support for those features.

I built the project keyboard one, so you don't have to ask for signoff ;)

Satisfaction75 has too much custom stuff

I think the fact that there's some question as to whether this would break other non-cannonkeys boards requires a bit more investigation.

Kinda leaning towards waiting until future branch gets merged before revisiting this, mainly as any of the chibios conf changes will collide, and any of the other boards that were direct copies of cannonkeys F072 will end up being a problem.
