This PR adds RTL support to RemoveJitsiWidgetView as the original code did not seem to consider RTL.
In RTL, translationX can be a negative value since it slides from right to left.
Therefore I updated translationXcalculation logic so that it can accept negative value in RTL.
Additionally, I modified the activation threshold check logic to use the absolute value of translationX since it can be negative in RTL.

Motivation and context

Fix #8210

Thanks for the pull request!

@ByeongsuPark do you confirm that it's still working as expected on LTR mode?
