RFR: 8235480: Regression: [RTL] Arrow keys navigation doesn't respect TableView orientation

[Ajit Ghaisas]

Bug : https://bugs.openjdk.java.net/browse/JDK-8235480

Fix : Added the missed out RTL checks to the key mappings in TableViewBehaviorBase class.

Testing : Modified unit tests in TableViewKeyInputTest to take orientation as a parameter. The Left/Right key press tests have been modified to address LTR and RTL orientations.

Note : If this test modification is acceptable, I would like to address other similar tests separately. (I will create a test JBS issue and address later)
