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/

- replace all instances of the deprecated iterator with the much nicer new one
- fix a bug which caused the new iterator to skip all values in the hash array
- fix a bug which caused the new iterator to skip the first value in the hash table
- delete the old iterator code
- also replace most uses of the deprecated string hash table iterator

Example:
```
bazel-out/k8-fastbuild/bin/protos_generator/tests/test_model.upb.proto.cc: In member function 'void protos_generator::test::protos::internal::TestModelV1Access::set_value4(size_t, int32_t)':

559 | assert(0 <= index && index < len);

There are several other functions which might eventually end up here and ideally become unified across json/ and text/ and io/ so this is just a first step to create the new subdir and get rid of upb/internal/

The next lowest build target to scrub is the hash table. We already have a few
other things called 'table' (mini table, fast table) so let's just go with
'hash' here. Split apart the headers into int and str branches sharing common
definitions. Leave the core functions in a single .c for inlining.

In order to flip the flag, all downstream projects should be adapted.
However, it is hard to fix them all if there are constant regressions.
Adding it to the CI will ensure that once the project can build with
incompatible_disallow_empty_glob it can keep building like that.

Move the map-related functions from msg_internal.h that are only used in generated code into map_gencode_util.h. Then move the rest of the map-related functions from msg_internal.h into map_internal.h.

Proto3 optional fields should use a hasbit for their presence. But we had been giving them oneof layouts, which makes them unnecessarily large. This CL will shrink messages with proto3 optional fields, by using hasbits instead of oneof cases for them.
