Planck Matrix Fixes (#21196)

* fix non-default keymap compiling, initial matrix state, watchdog options

* fix: allow planck/rev7 to be used with ENCODER_ENABLE = no

* chore: update function name on all cases.

* remove old midi tone option

Co-authored-by: Ryan <fauxpark@gmail.com>

* fixes abhixec's planck keymap

* add audio enable condition to abhixec's planck keymap

* add audio enable condition to all muse includes

* Revert "add audio enable condition to all muse includes"

This reverts commit 9779e908970dbf7cf81b1a3f968ef2e85ae2b76f.

* Revert "add audio enable condition to abhixec's planck keymap"

This reverts commit 24c742a5e8ddd55c45ce9f1917b0cb237d4bf721.

* Revert "fixes abhixec's planck keymap"
