Fixed localization formatting for picker widgets

The data/time separators were picked from the string resources ("/",
":"). This however could create issues in terms of localization since
different locales could have different separators defined for their time
and date formats.
Switched to using DateFormat to extract a locale-based string pattern
for both date and time.
Also defined a new way of specifying the separators to cover the general
case of different locales having different set of separators between the
time/date fields based on the current date/time format.
Also refactored different chunks of TimePicker.

Bug: 63715369
Test: DatePickerTest#testExtractSeparatorsForDifferentLocales,
TimePickerTest#testExtractSeparatorsForDifferentLocales
Also manual inspection of date/time widgets for several locales.
