Summary:
Implement common interface efl_ui_progress and inherit slider and progressbar from common interface.
Currently legacy APIs will also call interface functions and later it can be deprecated.
This interface will be moved to EFL in src/lib/efl/interfaces when elementary is merged into efl.
Test Plan:
elementary_test -to 'slider'
elementary_test -to 'progressbar'
