Encoder-in-matrix "hack" removal

[adophoxia]

Description

Updates the JSONs that uses the action_exec hack for fake encoders to instead use encoder mapping (e0, e1, etc. for the encoder button).

The updating process, which involved:

• Removing fake encoder rotation keys
• Having to move around some keys to be accurate to where they are located physically
• Editing the layout indexes to be able to add encoder options on keys that already had existing indexes attached
• etc.

Note: I only did this for boards in the v3 directory since it'd be pointless to do the same for boards in src if they're eventually flashed with v3 firmware. There may be some boards that I might've missed, or wasn't included in #20389.
