Bug 1920547 [wpt PR 48311] - [Interop] Deflake pointerevent_click_dur…

…ing_capture.html, a=testonly

Automatic update from web-platform-tests
[Interop] Deflake pointerevent_click_during_capture.html

The test has been flaking for the auxclick action where the
middle-click drag is probably causing autoscroll in some platforms.

This CL changes the action to use the right mouse button instead, after
suppressing any context menu invocation.
