Right click button interactions

[billyb2]

What problem does this solve or what need does it fill?

Allowing right clicking on buttons would allow for unique behaviors on buttons depending on the type of click.

What solution would you like?

Instead of Clicked being a type of an enum, clicked itself uses the MouseButton enum so that a click can be left, right, middle, or otehr

What alternative(s) have you considered?

Having a RightClicked type, though it feels like code bloat since MouseButton exists.

Additional context

Any other information you would like to add such as related previous work,
screenshots, benchmarks, etc.

This would be very well handled with per-entity events, see #2116. The impl there is not far from complete, but needs perf optimization.

So we would have to wait for that to be merged?

I pushed a quick fix for that in #2324

It will probably change how that works with the UI rework, but it's a small enough fix to do it now 👍

This is now complete due to bevy_picking's creation and integration with bevy_ui.
