Fix bug #6140391 Make RTL awareness as an opt-in into the AndroidManifest

- introduce "supportsRtl" as a new application attribute in the AndroidManifest
- "supportsRtl" default value is FALSE (no RTL support)
- adapt the View layoutDirection and textDirection logic to take care of "supportsRtl" value
