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.
The next in a series of CLs to split upb/BUILD into subdirs.
Create mem/internal/
Delete the deprecated upb/arena.h and upb/alloc.h stub headers

The overall motivation for this interface is to consolidate many places in upb that are parsing wire format data directly.
This interface is not yet complete, but this is a good start. We have enough to port the wire format parsing in accessors.c to this interface. We can follow up by porting more places that do wire format parsing.

Moving the logic down to EpsCopyInputStream makes it easier to test and reuse this functionality.
We also implement aliasing for the final bytes of the patch buffer, which has never been supported before. We used to always force a copy for any data parsed out of the patch buffer at the end of the stream.
Much of this logic is ported directly from the C++ EpsCopyInputStream class.

This mirrors the structure of C++ protobuf, which has an EpsCopyInputStream class.
This will lay the foundation for making EpsCopyInputStream capable of true streaming, by reading its input from a ZeroCopyInputStream. It also lets us test EpsCopyInputStream separately from the decoder: see the new unit test that fuzzes upb_EpsCopyInputStream.
After this CL is submitted, the two decoders (the normal decoder and the fast decoder) should no longer be accessing the members of upb_EpsCopyInputStream.

Remove circular dependencies that were bouncing back and forth between
msg_internal.h and mini_table/, including:
- splitting out each mini table subtype into its own header
- moving the non-reflection message code into message/
- moving the accessors from mini_table/ to message/

This is a naming change only, with no functional change. We did replace one inline function that had only one caller, but the net effect should be a no-op.
I did remove several `return` statements for calls to certain `noreturn` functions. These had no effect but were intended to improve readability. However the unused "return" caused ClangTidy to throw warnings, so these have been removed.

Lots of changes but it's all just moving things around.
Backward-compatible stub #include's have been provided for now.
upb_Arena/upb_Status have been split out from upb/upb.?
upb_Array/upb_Map/upb_MessageValue have been split out from upb/collections.?
upb_ExtensionRegistry has been split out from upb/msg.?
upb/decode_internal.h is now upb/internal/decode.h
upb/mini_table_accessors_internal.h is now upb/internal/mini_table_accessors.h
upb/table_internal.h is now upb/internal/table.h
upb/upb_internal.h is now upb/internal/upb.h

Unfortunately a few of the Clang warnings did not have easy fixes:
../../../../ext/google/protobuf_c/ruby-upb.c: In function ‘fastdecode_err’:
../../../../ext/google/protobuf_c/ruby-upb.c:353:13: warning: function might be candidate for attribute ‘noreturn’ [-Wsuggest-attribute=noreturn]
353 | const char *fastdecode_err(upb_decstate *d) {

../../../../ext/google/protobuf_c/ruby-upb.c: In function ‘_upb_decode’:
../../../../ext/google/protobuf_c/ruby-upb.c:867:30: warning: argument ‘buf’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Wclobbered]
867 | bool _upb_decode(const char *buf, size_t size, void *msg,
I even tried to suppress the first error, but it still shows up.
