[ADD] calendar,lunch,web: weekly recurrent widget

with this commit we adding weekly recurrent widget, currently proeject and
calendar shows boolean for each day vertically but with this widget we displays
week days and its boolean horizontally.

Here widget will display first day as per language's week_start field, also we
adds FieldDependencies on custom widget and consider those FieldDependencies
while processing view node in basic_view.js

We add support of registry to contain owl custom widgets and add support
of rendering owl custom widgets.

Also with this commit we removes fields like sun, mon, tue etc. from view and
instead use "web_weekly_recurrence" custom widget to display boolean for each
week day.
