Distinct from any clear_submsg(), this clears the message contents and doesn't affect presence on parent (and also allows for clearing owned messages which don't exist as a field to be cleared).

The non-string field setters can bypass the vtables already, the string setters still go through the vtable path here because its more important to let them take an `impl SettableValue` to be able to set either a &str or a &ProtoStr already.

The purpose is to avoid duplicating the mapping of different types that are only relevant to the serializer but not to the exposed api (e.g. FIXED32 vs INT32)
Treat type=GROUP as rust-type=MESSAGE here which is all that is needed for us to support groups in the rust codegen.
The RustFieldType is parallel to the preexisting FieldDescriptor::CppType which _almost_ does what we need, but it treats Bytes and Strings as the same cpptype which Rust codegen doesn't.

Needed to pass in the message as a parameter to the clearer thunk!
Now the clear() augmentations in accessors_test.rs are working as expected.

Add convenience _opt for singular message fields.
Users can detect if the message is set or unset, and unwrap via into_inner.

This is the final CL (part 4 of 4) in the ProxiedWithPresence chain.
In the past, we had returned Mut directly for the `_mut` accessors.
This was a temporary engagement in order to get the other submsg machinery checked in.
As we prep for the finalization of v0.6, we can finally conform to the rest of the `_mut` getters.
$field$_mut now correctly returns $pb$::FieldEntry<'_, $msg_type$> as a part of this.
All test callsites have been updated to `.or_default` in order to test the mutational pathway as before.

For the cpp runtime, call the `Message::CopyFrom` method.
For the upb runtime, expose the message `MiniTable` and call `upb_Message_DeepCopy`.

accessors_test.rs is getting a bit unwieldy, approaching 1K LOC. This CL breaks out the repeated tests into their own file (accessors_repeated_test.rs), as we expect the tests here to grow. This follows the precedent of `accessors_map_test.rs`.

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 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].

$Msg$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.
