FJLabs Swordfish Layout Macro Refactor (#21234)

* physically arrange layout macro

Arranges the layout macro to QMK standards (left to right, row by row).

This change breaks compatibility with out-of-tree keymaps, because the
order in which the keycode arguments must be passed is changed.

* rename `LAYOUT_alice_all` to `LAYOUT_split_bs`

* add `LAYOUT_2u_bs` macro

Move `RGBLIGHT_LED_MAP` to data driven (#21095)
