msg.submsg().x() and msg.submsg().x_mut() should now be callable for strings and bytes. Main idea here was to return &[u8] for bytes (vs [u8]) and &ProtoStr instead of &str or &[u8] for strings.
This CL also expunges IsSimpleScalar.

We've had access to views for submessages for a while:
If you hit some_message.submsg().some_int(), you'll get a view for that int.
Until now, there hasn't been a way to get some_message.submsg_mut(), so we introduce the mutational pathway here.
We haven't added fully-functioning mutation, but this is a step towards that goal.
subview was inaccurate, so I've refactored and renamed: { accessor_fns_for_views, accessor_fns_for_muts }.

We shouldn't give easy access to the zeroed block, so let's pass in pbi::private to deter misuse.
Also saw that arena wasn't used mutably in a repeatedfield test, so let mut -> let;

We continue our foray into googletest-rust [1], this time with homegrown matchers.
Our unit tests will now be able to check is_unset() and is_set() for all types that implement ProxiedWithPresence. In practice, this boils down to [u8] and ProtoStr.
Note that we've broken out matchers_upb and matchers_cpp, similar to what was done with aliasing here [2].

We had previously commented out the upb portion of simple_nested_test.
This is because nonmutable getters have submessages being NULL by default.
This means that trying to fetch anything, like a simple scalar from that nested message would segfault.
This CL makes the externC return an Option<RawMessage> since we've discovered that upb can return NULL. This way, we can check for `None` and handle the NULL case appropriately.
We know that the NULL pathway can only come from terra upb, since
cpp automagically constructs submsgs if they don't exist.
We've augmented upb.rs to contain a scratch space that allocates a zeroed-out contiguous chunk of memory @64KB. Since a block of zeroed-out memory is a legit message from upb's point of view, we can provide $pbr$::ScratchSpace::zeroed_block() to upb in order to get the default submessage behavior we want from upb.
This block is lazily allocated upon first request. This means that a consumer of the cpp kernel will not incur an additional cost.

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.

$Msg$View is incorrect, we need to actually invoke the getter_thunks. We'll use void* to get us off to the races.
Sprinkled in TODOs as appropriate; and we'll tackle imports in another CL. For now, its important to return the actual raw message, and that's what this CL does for our base uses.

This is predominantly a wrapper around `BytesMut`, for simplicity.
Bytes and string fields are mostly the same, except for possible UTF-8 handling.
This also implements some minor parts of `ProtoStr` that were missed.

This is a step forward for the full migration of Automatic Exec Groups (AEGs). This change will be effective once AEGs are enabled.
In this CL I've added a toolchain_type to `toolchain` attribute of ctx.actions.{run, run_shell} since the Execution platform is selected on a toolchain type level, not on a rule level like before AEGs.
