Added double clicking to all buttons on Linux and Javascript

Before only windows supported double clicking on all buttons. Javascript didn't have double clicking at all and linux and OSX supported double clicking only on left/primary mouse button.

This PR adds double clicking support on all buttons for linux and javascript. For javascript to function properly #20081 is needed or there won't be release event after double click.

It might be better if someone else implements the OSX support, because I don't have a mac and the current implementation is quite different. Though it could be changed to similar to linux and javascript.

Fixes #20042 (closed). Not on mac obviously.
