Add selection cycle and gray pre-selection outlines to the Path tool, and Tab to swap Select/Path tools (#2818)

* Added initial version of this feature for the path tool

* Removed debug statements

* Thickened the overlay width

* Added hover highlighting for path tool

* Experimental switch to path tool at leaf layer

* Ghost outline initial implementation

* Added tab swap for select tool -> path tool

* Minor fix for Select Tool dbl click -> Path Tool

* Added support for ghosts when using GRS in the path tool

* Fixed GRS undo bug, vastly improved hover behavior and now clearly visualize next double click target

* Fixed unused import warnings

* Updated behavior to handle mouse movement cases, reverted line width to 1px

* Fixed merge behavioral issues

* Disabled Select Tool to Path Tool double click toggle, fixed single click drill through for special case

* Clean up of unused consts and comment

* Properly cancel the drill through state when the mouse moves

* Fix some stuff
