Closes #7861: position text based on layout direction, not text directionality

[mavduevskiy]

Getting back to the RTL PR that caused regression and was reverted.

We use android:textAlignment="viewStart" already in many text views in the app, but not in every textView, which makes the UI inconsistent for RTL locales. Setting supporting RTL text alignment in styles does look like the right way of doing it.

The problem that the first PR caused: android:textAlignment overrides horizontal gravity. Views that had manually set gravity (center, center_horizontal) got broken because of that.

I tried to change the layouts as little as possible, adding the cener textAlignment for the textViews that want the text to be in the middle while having 0width.

As a follow up, I will remove manually set android:textAlignment="viewStart" in textViews, since the code is duplicated.
