For LITE messages we append the type name to the data, avoiding an
indirection and a relocation.
For descriptor messages we mark them as such and have a secondary vtable. This
way we avoid having to put those pointers on each message ClassData. We save in
data size and relocations. If in the future we determine that the extra jump is
costly we can inline the relevant descriptor method pointers into `ClassData`.

We do not want to repeatedly check `using_sso` when iterating over an array. Hence instead of using `Get(i) / Mutable(i)` from base class, we request a pointer to the underlying array (thus, reducing number of checks from N to 1).
Additionally, there is a loop with a `Delete` call - updated it to use `CommonHandler`, so that it reduces code bloat.

The new rules are:
- `upb_minitable_proto_library()`: contains the MiniTables only
- `upb_c_proto_library()`: Contains the C API. Depends on the MiniTables
This involved splitting upb code generation into two separate aspects, one for MiniTables and one for the C API.

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.

We plan to unify protobuf and upb into a single Bazel repo, but for now they
are separate repos as far as Bazel is concerned. This change will make upb's
workspace depend on the local copy of protobuf so that protobuf changes take
effect immediately for builds inside upb's workspace. This also mimicks the way
that the protobuf workspace depends on upb.

Our automation clobbered a few more files, so let's move them
temporarily so that we can put them back in place in a way that "git
blame" continues to work.
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.
