[Keymap] Update personal userspace and keymaps (#6654)

* Enable Fn layer tap dances only if LAYER_FN is defined

* Update KBD6X keymap spacing to match LAYOUT spacing

* Add regular FNLK to userspace, update keymap comment labels

* Rename KC_BRK → BREAK, KC_SYSR → SYSRQ in userspace

* Change mousekey positions in KBD6X

* Disable Console in KBD6X to reduce firmware size

* Return false in process_record_* only when overriding existing keys

* Fix Caps light not working after LSFT_FN

* Refactor Fn/Caps light, fix sequencing issues
