No doc links for quoted reflection methods

[nicolasstucki]

It is currently impossible to access the documentation of methods in the reflection API. http://dotty.epfl.ch/api/scala/quoted/Quotes$reflectModule.html

For example, TermMethods is listed but it is impossible to follow the link and find the docs for Term.tpe.

I think this is due to a name collision between terms and types, it seems the TermMethods trait isn't listed at all.
