Fix inline tag help for fields that handle multiple tags

Some preset fields like the access-restriction field manage
multiple tags at once (access=*, foot=*, bicycle=*, …). Then
iD wasn't able to show inline help when clicking the ⓘ button.

This introduces a new parameter for these kind of fields:
`referenceKey` determines the tag key which should be used to
search taginfo documentation for.

Fixes #2222.
