TGUI Color Picker (#26326)

* Init

* Implements `tgui_input_color`

* Implements most color wheel conversions to TGUI

* Iteration two, went over titles and made sure most color inputs are functional.

* Implements preferences for large buttons, swapped buttons, and disabled TGUI

* Iteration three... the weird ones. (as null|color)

* Removes `as color|null` and `as null|color`

* Merge conflict resolution, again.

* Color input bundle and panel bundle

* CSLint being picky.

* Picky `while ()` instead of `while()`

* Apply suggestions from code review
