General test for it is done in Rust, and then extensions are tested in UPB as they're not currently supported in Rust-upb.

We modify set_<repeated_field> to accept the IntoProxied type as the value and move the value (avoid copying) whenever possible.
For UPB:
- We fuse the arena of Repeated<T> with the parent message arena.
- We use upb_Message_SetBaseField to set the upb_Array contained in the Repeated<T>.
For C++:
- We generate an additional setter thunk that moves the value.
- The move assignment operator of RepeatedField/RepeatedPtrField is specialized. In order to adhere to the layering check we need to add '#include' statements for all .proto imports to the generated thunks.pb.cc.

The intent of this directory would be for a layer of Rust bindings that directly map to upb semantics; Rust Protobuf runtime would be layer on top of that Rust, instead of directly on the upb C api.

For the cpp runtime, call the `Message::CopyFrom` method.
For the upb runtime, expose the message `MiniTable` and call `upb_Message_DeepCopy`.

This change moves almost everything in the `upb/` directory up one level, so
that for example `upb/upb/generated_code_support.h` becomes just
`upb/generated_code_support.h`. The only exceptions I made to this were that I
left `upb/cmake` and `upb/BUILD` where they are, mostly because that avoids
conflict with other files and the current locations seem reasonable for now.
The `python/` directory is a little bit of a challenge because we had to merge
the existing directory there with `upb/python/`. I made `upb/python/BUILD` into
the BUILD file for the merged directory, and it effectively loads the contents
of the other BUILD file via `python/build_targets.bzl`, but I plan to clean
this up soon.

A couple weeks ago we moved upb into the protobuf Git repo, and this change
continues the merger of the two repos by making them into a single Bazel repo.
This was mostly a matter of deleting upb's WORKSPACE file and fixing up a bunch
of references to reflect the new structure.
Most of the changes are pretty mechanical, but one thing that needed more
invasive changes was the Python script for generating CMakeLists.txt,
make_cmakelists.py. The WORKSPACE file it relied on no longer exists with this
change, so I updated it to hardcode the information it needed from that file.

In this CL we're adding the barebones infrastructure to generate Rust proto messages using UPB as a backend. The API is what we call a V0, not yet production-quality, not yet rigorously designed, just something to enable parallel work.
The interesting part of switching backend between UPB and C++ will come in a followup.
