RFR: 8330559: Trailing space not rendering correctly in TextFlow in RTL mode

Fri May 31 14:43:13 UTC 2024

The issue is specific to Mac. The glyph positions returned from native side for complex text is not handled in the text render logic. This issue is observed only when trailing spaces are present along with LTR text mixed with RTL text (Example: "Arabic: العربية").

Made changes in `getPosX` of `TextRun` class to handle negative values.

Tested the changes manually with the sample code present in the bug and using the MonkeyTester.
