This CL is mostly a no-op, except that now google3-only code is actually stripped from OSS, instead of being preserved in `# begin:google_only` blocks.
This follows the conventions of the greater Copybara ecosystem.

This simplifies upb by removing differences between google3 and OSS.
This also points upb at the protobuf license, instead of keeping a separate copy around for upb.

This is needed to make protobuf/bazel package minimal for other proto rules.
Keep 4 public bzl files in upb/bazel. They end up under protobuf/bazel, and they are legitimately used by other repositories.
Move upb_proto_library_internal/* under bazel/private. Those are utilities used in the rules. Moving them one level deeper makes protobuf/bazel package clean for other rules.
Move build_defs.bzl and amalgamation under /upb/bazel. Those are utilities used in the build.
Move lua.BUILD and python* uner /python/dist. Those are used in the WORKSPACE dependency setup.

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.

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.

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.
Any public interface should not be marked incompatible, since the @system_python repository is specific to *this* workspace. Downstream users can name it whatever they want or use a hermetic python build, in which case this repository won't be defined.

The current behavior will crash any Bazel command immediately, due to our declared pip dependencies in WORKSPACE, if python3 can't be found. The new behavior will mock out these workspace dependencies and allow any non-python targets to run. Python targets will be skipped by wildcard expressions if there's no system python3, and will fail when run directly, due to compatibility mismatch.
