TH.Lift instance for Name

Motivation

There is no Lift instance for Name. There used to be one in th-lift. I'm not sure if there's a good reason not to have this, but otherwise it would be nice to have.

The example where I wanted this is something like this: I'm generating a lot of types in a TH splice, and I want to also generate a list of all the type names that I can then use later (e.g. to call makeLenses on them in another module).

Proposal

Add an instance.
