Fix layouts containing keys with multiple matrix positions

[fauxpark]

Description

Should be everything that would be flagged by #20039.

Cross-checked with VIA JSON (assuming it is correct) or schematics (converter/a1200) where available. The rest are best guess based on the key names in the layout macro.

jian's symmetrical layouts also had to be removed and replaced with normal layouts. This comprised the majority of the validation errors since every key was duplicated and there are four revisions of the board.
