add ttys0's planck and preonic keymaps (#10560)

* resynced with upstream, and adjusted keymap layout for planck

* updated keyboard layout

Signed-off-by: Sean Johnson <sean@ttys0.net>

* swapped out bspc for del on symb layer

Signed-off-by: Sean Johnson <sean@ttys0.net>

* fixed typo with brightness media keys

* turns out my brightness config was correct, it was macOS that had gone sideways

* updated to bring in line with requirements for merging into upstream

* removed redundant config from rules.mk

moved media controls to FUNC layer for Planck layout

* added GPL2+ compatible license header
