Auto merge of #26051 - Manishearth:openxr-context, r=jdm

Hook up new openxr context menu gesture to embedder context menu machinery

Based on https://github.com/servo/servo/pull/26043/

Fixes https://github.com/servo/servo/issues/25797, #26057

https://github.com/servo/webxr/pull/144 needs to land first

Currently when exited the Servo window is blurred, apparently we need to call `Window.Activate` on it.
