Apparently VIA allocates bits in the layout options field from the
lowest bit, but starting from the **last** option defined in the JSON
file. So the default value 0x06 was actually trying to set the value
`3` (`0b11`) for the second-to-last option ("Right Shift"), which had
only 3 values defined, and the attempt to set an undefined option value
caused the VIA app to hang with a black window.
Fix the default layout options so that it works as intended (the
"Macropad" and "65% Column" options are set).
* Add support for Caps Lock LED
Currently ignores the fact that led_state is not synced between halves, so caps lock LED doesn't do anything if USB is plugged into right half
* Set initial backlight and RGB mode/values on blank EEPROM
* Set default VIA layout options
* Add backlight/RGB ifdefs
* Set bootloaders for each rev
* Enforce definition of `DIODE_DIRECTION` for non-custom matrix boards
* Define diode direction for failing boards
* Matching parentheses
* Put onekey diode directions in top level config
