LPS-43250 Invert resize behavior directions on RTL

Hey Iliyan, this PR reverts the previous fix, which was masked by https://issues.liferay.com/browse/LPS-43612 and caused us to commit an incorrect fix.

With that one working, we've added some additional rules on R2 to handle the correct position and visualization of the handles, and a small module on portal to invert the resize behaviour in the RTL case.
