Apply improved autodeps

Summary:
Apply autodeps improved in D60528917 to Thrift. This removes more than a thousand of unnecessary exported deps:

```
arc lint -a -- `find thrift -name BUCK`
arc lint -a -- `find thrift -name TARGETS`
```

This revealed missing dependencies in `common/thrift` (fixed by applying autodeps there as well) and `caffe2` (fixed manually since their build config is a bit of a mess).

Add a missing include to `thrift/lib/cpp2/async/ClientChannel.cpp`.

Mark a few targets that previously failed to build in xplat as fbcode-only so that they are not even generated there.
