CannonKeys Balance Layout Macro Additions and Touch-Up (#20548)

* add matrix_diagram.md

* refactor default and via keymaps

- use four-space indent
- grid-align keycodes

* info.json: apply friendly formatting

* standardize default and via keymaps

Place the `KC_NUHS` and `KC_NUBS` keycodes on the correct keys.

* add LAYOUT_ansi with reference keymap

* add LAYOUT_ansi_split_bs with reference keymap

* add LAYOUT_iso with reference keymap

* add LAYOUT_iso_split_bs with reference keymap
