kbdfans and dztech cleanup

[kb-elmo]

Description

Big cleanup of all newer KBDfans and DZtech keyboards/PCBs (I didn't really touch the old ones that aren't manufactured/sold anymore).

Changes:

• Cleaned up the config files
• Cleaned up the default/via keymaps and changed some of them to be a bit more "standard"
• Re-enabled most RGB animations on the RGB PCBs since there is no need to disable them. The boards have plenty of flash for those. I kept some of the more redundant looking ones disabled on the request of KBDfans.
• Removed the USB startup check on all boards that had it set. This is known to cause issues with the board not starting up after rebooting the computer
• Changed the debounce on all PCBs back to the default 5ms. People have been reporting chattering issues on some boards where it was set to 3ms
• Moved the DZ60 into the DZtech directory with all his other PCBs
• Changed the directory structure for the KBDfans Maja to match the other KBDfans boards
