OnWheels: Add icon for inaccessible elevators, etc.

[danieldegroot2]

Suggestion: Similar to disabled drinking water, show red cross or other icon for inaccesible -and/or disabled- elevators, etc. . ( 🚫 access=no )

Note, may be mixed with some disabled ones, and some excessively tagged (combined with opening_hours, etc.) May also need an icon for wheelchair=no in this case.
