Filter screens consolidation

[rh12]

refs: MBL-18544
affects: Student, Teacher
release note: Improved various filter screens.

TODO

• Check VoiceOver support
• Unit tests
• Previews (may skip for now, because it's not working at the moment)

What's changed

Added SingleSelectionView and MultiSelectionView components (and their viewmodels) to handle selections, typically found on Filter or Preferences screens.

Added OptionItem as the model for these, which is a stripped down, unified model for all option selections.

• It is intended to be created from and match with the given domain model.
• Helper types SingleSelectionOptions and MultiSelectionOptions group them together for simplified usage.
• Kept its id as a String instead of making it generic. For simplicity and because it covers most cases.
• It has no related protocol like OptionItemConvertible at the moment.

Updated the following screens to use these:

• Student Assignment List Preferences
• Teacher Assignment List Preferences
• Grade List Preferences
• Smart Search Preferences
• Calendar Selector
• Calendar Filter

Consolidated UI in accordance with UX designer (Figma update is WIP)

• components (RadioButtonCell, CheckboxCell, ListSectionHeader, Divider)
• unified the above preferences screens (consistent wording, ordering, etc.)

What's not changed

• List screens are not updated to use the updated components
• Colors are not following context color yet
• Navigation Bar (button fonts + colors, title fonts, dynamic text sizes)
• Grade List Preferences screen Done behaviour:
  • swipe-to-dismiss is not added yet
  • kept "Done" button disabling for now
• Did not refactor/rework types around the affected screens, tried to draw the line somewhere

Test plan

Verify all the above screens work as before, including the interactions with their List screens.
There is no updated Figma for each of the screens, so please check the screenshots below for UI changes.
