A bunch of commits I should've split apart but weh

 - Removes Pico presets (as there never was any real presets for it to begin with)
 - Removes ItsyBitsy Samco 2.0 preset (as it's just the same as the board default)
 - Changes IR Layout to a combobox instead of toggle, making it much clearer what setting corresponds to what.
 - Presets Box in the pins layout tab is now hidden by default, and only unhides when at least one layout exists for the board.
 - Changes Presets Box placeholder text to "Select Layout Preset"
