Significantly improved performance by adding caching of combinational chips

[CC56785]

Purely combinational chips, so chips whose outputs entirely depend on their inputs and on nothing else, who also don't have too many input bits, now get cached. This means that a look up table (LUT) with 2^(number of input bits) entries gets created and whenever this chip needs to determine its output, it can just use the LUT to immediately know what its output should be.

This usually gave me a speedup of up to 4x (for example my CPU went from 1500 sps to more than 5000 sps).

Also added some UI in the chip customization menu where the player can decide for medium sized chips whether they should get cached or not.
Also added a little pop up info to give progress information when creating large caches.

Any special cases (like displays, keys, tristated values, view mode, ...) also all get handled correctly (usually by turning off chip caching).

Hey is this fully functional without any problems?

Yup, I set it up in a way so that it should exactly mimic the games normal behavior.
From the two Projects I tested it on in this Video, it also seems like it is indeed working perfectly.
