Add ADA Features Filter

[avaleske]

Add filtering based on ADA accessibility features, on the building or on the listing. See #609 for the fields added to the database.

Some notes:

• We only have data on the building, not the specific unit, so that will need to be reflected in the frontend filter (see Clarify language around "ADA Compliant" filter and reserved community type filter and pill #591)
• Should the filter be a checkbox, or dropdown that lets you select "some units in building have features" or "all units in building have features"?

Design for this is viewable in Figma (02.2). Only caveat is that it should read 'Laundry in building', not 'Laundry in unit'.
