Keyboard: Added support for GSKT-00 (#3911)

* Added QMK support for GSKT-00, PaladinSplit, PaladinTKL and PaladinPad pcbs

* Remove the paladin boards from this PR

* Changed gskt00 as per review comments. Added two new default layouts, 60_ansi_tsangan and 60_iso_tsangan

* Fix the layouts/default/60_iso_tsangan/layout.json file

* Removed ? from rules.mk, removed unused fn_actions from keymaps. Changed the 60_iso_tsangan to work correctly

* Removed PREVENT_STUCK_MODIFIERS
