Android: Handle light/dark mode changes

Update Theme's style according to current UiMode.

New style.json file for dark mode was added (stored in separate
subdirectory 'darkUiMode/'). Theme_DeviceDefault_DayNight[0] is used for
extraction for API 29 or higher. Style is updated each time when UiMode
is changed.
