Move mouse event disabling on interactive elements to SimpleEventPlug…

…in. Related perf tweak to click handlers. (#7642)

* Cull disabled mouse events at plugin level. Remove component level filters

* DisabledInputUtils tests are now for SimpleEventPlugin

* Add click bubbling test

* Add isInteractive function. Use in iOS click exception rules

* Invert interactive check in local click listener. Add test coverage

* Reduce number of mouse events disabable. Formatting in isIteractive()

* Switch isInteractive tag order for alignment

* Update formatting of isInteractive method
