These exist so that new features can specify their proto2/proto3 defaults. This will allow for easier migration to editions, and also allow us to migrate more proto2/proto3 code paths to common editions code. The latter will provide give us early coverage over a lot more of editions.

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

I also deleted some of upb's dotfiles that are either obsolete (like
`.bazelci/presubmit.yml`) or seem to be superseded by protobuf's dotfiles.

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.

This restores the Python wheel CI runs from the old upb repo with only minor
changes. I had to update a path in one of the `py_wheel` rules and also make a
slight tweak to ensure that the `descriptor.upb_minitable.{h,c}` files make it
into the source wheels. The change in text_format_test.py is not strictly
necessary but is a small simplification I made while I was trying to debug an
issue with CRLF newlines.
I had to update test_util.py to use `importlib` to access the golden files from
the installed `protobuftests` package. I suspect the previous incarnation of
thse test runs was somehow reading the goldens from the repo checkout, but I
think the intention is to read them from `protobuftests` instead. This was a
bit tricky to get working because Python versions before 3.9 do not support
`importlib.resources.files()`. I set up the code to fall back on
`importlib.resources.open_binary()` in that case, but that function does not
support subdirectories, so this required putting an `__init__.py` file inside
the `testdata` directory to make sure it is treated as a Python package.

I am getting ready to move almost everything under the upb/ directory up one
level to integrate upb better into its new location in the protobuf repo. This
change makes a few tweaks to prepare for that:
- Delete upb's LICENSE and CONTRIBUTING.md files since we already have similar
files at the top level.
- Rename `//python:python_version` so that it won't conflict later with
`//upb/python:python_version`.
- Move the contents of python/BUILD.bazel out to a Bazel macro to facilitate
merging that BUILD.bazel file with upb/python/BUILD.

Prior to this CL, upb MiniDescriptors only allowed per-message control over UTF-8. This CL adds a new field-level modifier to upb MiniDescriptors that can flip a field to the opposite of the message default, like we already have for packed, allowing per-field control over UTF-8 validation.
