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.

I merged a handful of PRs on the upb repo after upb moved into the protobuf repo. This PR cherry-picks them here so that they will not be lost.

[bazel] Fix disallowing dylibs on darwin (#1180)
Since this bazel commit
ec5553352f
building dylibs like the ones in this rule on darwin platforms has been
unsupported. This feature is a default C++ toolchain feature to indicate
this. In bazel 7.x these dylibs will fail to link if they are still
built. As far as I can tell in the tests even if they are built they are
never used on macOS.

Add missing darwin_x86_64 CPU (#1181)
This CPU is often used when cross compiling from M1 machines. I'm also
hoping we can remove the legacy 'darwin' CPU.

Fix `PyUpb_Message_MergeInternal` segfault (#1338)
when `PyUpb_Message_MergeFromString` returns `NULL`, currently
`PyUpb_Message_MergeInternal` will call `Py_DECREF` on `NULL`
which results in a segmentation fault.
This patch switches to `Py_XDECREF` to fix the segfault.

Fix lambda capture compiler error with c++20 (#1502)
When compiling with C++20, the following error is produced:
```
upb/mini_table.hpp:63:22: note: add explicit 'this' or '*this' capture
upb/mini_table.hpp: In lambda function:
upb/mini_table.hpp:71:22: error: implicit capture of 'this' via '[=]' is deprecated in C++20 [-Werror=deprecated]
71 | return appender_([=](char* buf) {
```
In C++20, it is no longer allowed to implicitly capture 'this' in a
lambda using [=].
This commit explicitly captures required values in the appropriate
lambdas and removes all uses of [=] with lambdas.
```

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.
After this change, `mini_table` only has MiniTable definitions themselves. Everything having to do with the MiniDescriptor wire format is in `mini_descriptor`.
Also rearranged some of the files in mini_table to have better structure for `internal/`.
This CL contains no functional change.

This required some work to unify map entry messages with regular messages, with respect to presence. Before map entry fields could never have presence. Now they can have presence according to normal rules. Note that this only applies to times that the user constructs a map entry directly.

We need to sharpen the distinction between messages and extensions in the mini
descriptor encoder, so split the code paths for each.
PiperOrigin-RevId: 480675339
An enum MiniDescriptor simply encodes a set of valid `int32_t` values, so that the protobuf parser can test whether a given enum value is known or not.
The format implemented here is novel and needs to be documented. In short, the format is:
1. base92 values 0-31: 5-bit mask indicating presence or absence of the next five enum values.
2. base92 values 60-91: varint indicating skip over a region of enum values.
Negative enum values are encoded as their `uint32_t` equivalent.
