I also added a blanket implementation of `IntoProxied<T> for T` so that we
don't have to duplicate this no-op implementation for all our types.

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).

Adds a new 'bzl' feature that is used to adjust import paths that need to change
in the Cargo build vs Blaze build.
This protobuf rust crate is a single crate that merges all of our current crates (protobuf, rust/upb, and utf8).

Default to collecting unknown fields as data and then create the
`GPBUnknownFieldSet` on demand when requested.
This should reduce the as the extra objects are created until requested
and clears the way to eventually deprecated `GPBUnknownFieldSet` in the
future.
This also fixes the failing conformance test related to keeping the ordering.

We have received several reports in #17036 that the addition of this flag
actually broke the use of command argument files with non-ASCII characters in
their names. It looks like #14253 ended up fixing the original issue with a
different solution anyway. Hopefully this change fixes the issue with non-ASCII
characters.

- Add overloads that take `absl::Cord` and `std::string&&` as inputs, putting the burden in the implementation instead of users.
- Add overload that returns `absl::Span<char>` for callers that need higher performance requirements where we can avoid copies altogether.
- Hide the APIs that return `std::string*` when the breaking change is enabled (via `-D PROTOBUF_TEMPORARY_ENABLE_STRING_VIEW_RETURN_TYPE`).

- We introduce two new view types ProtoStringCow and ProtoBytesCow.
- In UPB, for cord field accessors we always return a Cow::Borrowed.
- In C++, for coed field accessors we check if the underlying absl::Cord is flat (contigous) and if so return a Cow::Borrowed. If it's not flat we copy the data to a ProtoString and return a Cow::Owned.
- We expect the absl::Cord to be flat almost all the time. We have experimentally verified that for small strings (<4 KiB) and less than 6 appends the cord is in fact flat [1].
- This change lifts the requirement of all ViewProxy types to be Copy. Our Cow types cannot be Copy because the owned types aren't copy.

`GPBTextFormatForMessage()` will contain any information for unknown fields.
And it clears the way for `GPBUnknownFieldSet` to eventually be deprecated
also.

GenerateByteSize itself remains deeply nested, but by factoring out one part of
the loop, at least we make the part that generates UpdateByteSize a bit more
readable.
Making the callsite of MayEmitIfNonDefaultCheck less nested actually resulted
in slight readability improvements also in the generated code, namely of the
form:
@@ -10563,8 +10559,7 @@ PROTOBUF_NOINLINE void OneStringEdition:
{
// string data = 1;
- cached_has_bits =
- this_._impl_._has_bits_[0];
+ cached_has_bits = this_._impl_._has_bits_[0];
if (cached_has_bits & 0x00000001u) {
total_size += 1 + ::proto2::internal::WireFormatLite::StringSize(
this_._internal_data());
These readability improvements should be kept IMO -- they make the generated
protobuf C++ code slightly easier to read.

The toolchain type is consumed by proto_library and produced by proto_toolchain rule. As such it's a private dependency, because both rules are now part of protobuf repo.
There are some early adopters of --incompatible_enable_proto_toolchain_resolution that might be broken from this: grpc, rules_go, rules_ts, rules_rust, rules_lint, because they have implementation that is not using proto_common. Those repositories need to define their own proto_lang_toolchain and consume it with proto_common.compile.

Make a new internal api for collecting up the unknown group fields
that will be used in a future change.
Add testing for the new api and for unknown field parsing of groups in
general.
