RFR: 8323880: Caret rendered at wrong position in case of a click event on RTL text

[Jay Bhaskar]

Issue: The current implementation of complex text rendering paths on the Java platform is experiencing side effects. 
Solution: We need to align with WebKit 616.1 standards. The patch supports two paths simple rendering path and complex rendering path based on text rendering mode.
