[Foundation] Create a new NSAttributedStringDocumentAttributeKey enum to match Apple's headers.

[rolfbjarne]

This allows us to unify the code between all platforms.

Also add all the NSAttributedStringDocumentAttributeKey values we haven't bound yet.

There are no changes in the public API, because I'm only changing internal types.

Ref: #14489.
