[Tooling] [1/1] Refactor FrontendActionFactory::create() to return std::unique_ptr<>

Summary:
I'm not sure whether there are any principal reasons why it returns raw owning pointer,
or it is just a old code that was not updated post-C++11.

I'm not too sure what testing i should do, because `check-all` is not error clean here for some reason,
but it does not //appear// asif those failures are related to these changes.

This is Clang-tools-extra part.
Clang part is D43779.
