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.
Remove array.h and map.h as hdrs from :collections_internal
Remove alloc.h and arena.h as hdrs from :mem_internal (and add them to :mem)
Remove common.h and decode.h and encode.h as hdrs from :wire_internal
Lock down the visibility of :wire_internal to upb-only
Merge :mini_descriptor_encode_internal into :mini_descriptor_internal

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.

Since promotion is a more complicated operation than the simple accessors, and since promotion logic will likely be changing before long, it helps to put promotion-related logic in a separate place and rule.

The fields of upb_MiniTableField are intended to be internal-only, accessed only through public functions like `upb_MiniTable_GetSubMessageTable()`. But over time, clients have started accessing many of these fields directly. This is an easy mistake to make, as there is no clear signal that the fields should not be used in applications. This makes the implementation difficult to change without breaking users.
The new `UPB_PRIVATE()` macro appends an unpredictable string to each private symbol. This makes it very difficult to accidentally use a private symbol, since users would need to write something like `field->submsg_index_dont_copy_me__upb_internal_use_only`. This is still possible to do, but it leaves a clear wart in the code showing that an an encapsulation break has occurred. The `UPB_PRIVATE()` macro itself is defined in `port/def.inc`, which users cannot include directly.
Once we land this, more such CLs will follow for the other fields of `upb_MiniTable*`. We will add inline functions as needed to provide the semantic functionality needed by users.

Currently these functions are hardwired to always return true, but the upstream
code now checks for failures (which will be implemented soon).

- Rename the accessors from upb_MiniTable_Foo() to upb_Message_Foo()
- delete _upb_Message_Clearext() which is now redundant
- Allow the getters and setters to accept both extension and non-extension fields
- Add a (upb_Arena*) param to setters (only needed for extensions)
- Change setters from void to bool (since extensions may require allocations)
PiperOrigin-RevId: 493760399
_upb_MiniTable_Build() is now the general version of the function;
upb_MiniTable_Build() calls it and sets the platform to default/native.

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/

We had _upb_Message_New(), which created a message from a mini table and was
being used outside of upb even though it is an internal-only function.
We also had upb_Message_New(), which created a message from a message def.
Now there is a single public function, upb_Message_New(), which creates a
message from a mini table and covers all use cases. (The internal version has the same definition and is used for inlining.)
PiperOrigin-RevId: 480169804
- Each def type has its own .c file and its own .h file
- Functions that require a builder context are declared in def_builder.h
- The mini descriptor encoders have also been pulled into upb/reflection/
- upb/def.h, upb/def.hpp, upb/reflection.h, and upb/reflection.hpp are now deprecated stubs that point to the new headers
PiperOrigin-RevId: 474459500
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
