Pull Request Overview
This PR addresses an RTL (right-to-left) scrolling offset issue in iOS by introducing a conditional layout rearrangement when the UI direction is RTL.
- Added conditional block in LayoutSubviews to adjust content arrangement and offset based on EffectiveUserInterfaceLayoutDirection
- Sets the content offset to ensure correct scrolling behavior in RTL environments

[nitpick] Consider extracting the expression 'crossPlatformBounds.Width - contentSize.Width' into a variable to avoid duplication and enhance readability.

I wish there was a "Asking a question" button, but I have to pick an option or the bots bug me to pick something.
But, it appears the layout for RTL uses the right of the visible area, so a negative left offset will move the content or move the start and show the content?
