[Keyboard] Assorted personal keymap/layout updates (#6621)

* Switch Quefrency back to I2C (#6161 fixes the lag)

* Update Quefrency keymap

* Add reset and EEPROM reset keybindings so these tasks can be performed
separately, rather than relying on Bootmagic Lite, which performs both
tasks at the same time.

* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.

* Update KBD67 keymap

* Add reset and EEPROM reset keybindings so these tasks can be performed
separately, rather than relying on Bootmagic Lite, which performs both
tasks at the same time.

* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.

* Move Menu to a layer tap on the Fn key since that's a more natural
location.

* Update 60% Tsangan HHKB layout

* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.

* Update 60% ANSI split backspace/right-shift layout

* Add reset and EEPROM reset keybindings so these tasks can be performed
separately, rather than relying on Bootmagic Lite, which performs both
tasks at the same time.

* Move Caps Lock from Fn+Ctrl to Fn+Tab since Fn+Ctrl is sometimes used
as part of a more complex keybinding, whereas Fn+Tab is always safe.
