Sema: Don't apply access level fix-it to @dynamicMemberLookup subscript.

Browse Source 
The adjusted access level for the subscript shouldn't be fixed automatically
since sometimes the diagnostic is a warning and other times automatically
applying the fix-it immediately causes other errors, which can be confusing.

Resolves rdar://158261884.
