Fix Some Date and Time parsing cases

[tarekgh]

Fixes #61708

This change fixes two issues with the parser:

• ICU provide some DateTime formatting patterns for BiDi cultures which include the Unicode Right-toLeft mark U+200F. This mark mainly helps when displaying the formatted date and time but it doesn't have any effect on the values or the separators. Our DateTime parser was not recognizing such mark and fails with any date/time strings containing such mark. This fix is addressing that by skipping this mark during the parse operation.
• Some cultures like dz-BT started formatting time with space separators. Something like 10 30 PM. The parser was failing with such case too and this change is fixing it.
