This is a breaking change since the JSON parser will now correctly reject certain bad inputs that it previously silently accepted (for example: json="{}x" was accepted).

This required enabling the feature in the code generator and fixing a few edge cases around label and type.
Also added tests to verify the special cases, and to verify that required fields work as expected.

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.

pkg_files() has some odd quirks, like breaking if a filename exists in multiple directories. filegroup() does everything we need, without these quirks.

C++20 requires that types used in std::vector are complete. Group's constructor definition requires that UnknownFields' destructor be available, which means UnknownField must be complete.

- Fixed a couple of broken tests that were probably invoking UB.
- Excluded python/... and js/..., as these do not work with Windows.

This was not a bug -- the previous behavior was correct. However this
change brings our implementation-specific details in line with C++.

Previously we were calling the static method `Equals()` which did not take into effect the custom comparator or string for reporting errors.

The initial motivation for this change was to fix a bug found by fuzzing. The old fuzz test (built on `cc_fuzz_target()`) detected an infinite loop if a bytes field default has an unterminated `\x` escape.
To fix this bug while expanding fuzz coverage, I created a fuzz test that verifies that we can do a lossless round trip from descriptor -> DefPool -> descriptor. We use C++ as the source of truth for whether a descriptor is valid or not, and what the canonical serialization back to protobuf form should be.
I wrote the new fuzz test using go/FuzzTest, which makes it easier and more readable to use an arbitrary `FileDescriptorSet` as input, while adding test cases for regressions.
The fuzz test highlighted a handful of errors that I subsequently fixed and added regression tests for:
1. The aforementioned unterminated `\x` bug.
2. We were not propagating the `edition` field.
3. We were missing the CheckIdent() check in a few places.
4. We were rejecting files with empty name, whereas C++ allows this.
5. There were a few bugs with escaping string defaults.
Since FuzzTest is Clang-only, I split the `FUZZ_TEST()` invocation from the regression tests, since the latter are portable and should be run on all platforms. Only `FUZZ_TEST()` itself is in a google3/Clang-only file.

According to https://en.cppreference.com/w/c/program/setjmp automatic variables
modified in a function calling setjmp can have indeterminate values. Instead,
refactor all functions calling setjmp so that the function calling setjmp
doesn’t have any local variables.

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.

update upb to use upb_Map_Next()
remove upb_MapIterator_SetValue(), which was declared but not actually implemented
remove upb_MapIterator_Done(), which was implemented but not actually used
