This makes the file layout a bit more consistent with the `protos ->
protos_generator` pattern. I also replaced the `upbc` namespace with
`upb::generator`.

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.

This is the second attempt to fix our Git history. This should allow
"git blame" to work correctly in the upb/ directory even though our
automation unexpectedly blew away that directory.
It ended up being odd to construct the AccessorGenerators ahead of time given some specific Context<>: since each of the three methods on AccessorGenerators demands a different Context than the initial one so they shouldn't hold that Context anyway. It ended up just being a spooky parallel array to the Fields with an unenforced invariant that all methods would be called with a new Context<> but the same underlying FieldDescriptor later.

This CL sets up the basic plumbing end-to-end for singular message fields.
We add skeletonized support for `Proxied` messages. This is done
by creating structs for $Msg$View and $Msg$Mut, and providing
stubbed impls.

The intent of this change is to take the best ideas from the C++ backend, such as having generator objects that can cache pre-computed state, while minimizing duplication.
Where possible, we take the approach of making the C++ and UPB kernel-specific code as similar as possible, since this reduces the number of templates we need to keep in sync.
