Put the emission of braces and indentation into MayEmitIfNonDefaultCheck, this
allows for a slight beautification in the emitted code and reduces verbosity at
the call site.
Also this technically fixes the indent in some cases (specifically when
serializing some repeated fields) so that the opening braces are emitted "at
the right level".
(Previous implementations sometimes emit an extra space character.)
Compare:
{
// code ...
}
vs.
{
// code ...

GPBUnknownFields will be going away in the next major release of the ObjC
Protobuf runtime. Code should be updated to make use of GPBUnknownFields
instead.

We mostly use generated pom files in our release currently, so we can delete all the files that aren't used and the tools to update them.
Note, java/bom/pom.xml java/pom.xml and java/protoc/pom.xml are all still used at release and java/kotlin/pom.xml is used for documentation so all of those need to stay for now.

The arena and the heap representation are both aligned to 8 bytes so we can use the lowest 3 bits of the heap pointer to encode whether the RepeatedField is in SOO mode or not, and if it is in SOO mode, to record the size. Therefore, we can have SOO sizes from 0 to 3 and one bit for whether we're in SOO mode. Note that we also tried using 3 bits for SOO size with a sentinel value for not-SOO-mode, but that was slower.

Adds new tests in `//compatibility` for detecting undesired breaking changes in the schema of the well-known types and `descriptor.proto` files, using the Buf breaking change detector, via [`rules_buf`](https://github.com/bufbuild/rules_buf/).
In order to keep things light-touch as far as maintenance goes, I have chosen to keep the integration as small and simple as possible. Some notes:
- Breaking change behavior can be granularly controlled via [`buf.yaml`](https://buf.build/docs/configuration/v1/buf-yaml#breaking).
- Bazel sandboxes us away from meaningful VCS information, so in order to pick a target to check for breaking changes against, a new variable is added to `protobuf_versions.bzl` that needs to be updated with changes in the release version.
- Breaking change detection is performed on a file-level, not a package-level, so migrating types across WKT files would constitute a breaking change. If this is not desired the behavior can be made to work on a package-level, though we need to do some more work as `buf_breaking_test` currently only accepts a single file descriptor set target for the `against` attribute.

Store them as Object[], because you can't have a Entry[], because Entry[] has a generic 'this' over <K, V>, you get error "generic array creation" if you try to make "new Entry[]".
And if you try to cast Object[] to Entry[], you get ClassCastException. So I've just made it an object array that we cast when reading out of.
This should save memory and improve performance, because we have fewer pointers to chase.
Also fixed some warnings about unnecessary unchecked suppressions, and type-name should end with T.

By "string APIs", I mean the following APIs:
- mutable_foo
- set_allocated_foo
- release_foo
See also: https://protobuf.dev/reference/cpp/cpp-generated/#implicit-string
Add the following test cases (for singular implicit-presence fields):
- A single call to mutable_foo() should not result in additional serialization
on the wire.
- Assigning an empty string to mutable_foo() should not result in additional
serialization on the wire.
- Calling set_allocated_foo() with an empty string should not result in
additional serialization on the wire.
- If a field is nonempty, release_foo() effectively clears the field (while
returning a pointer to the original data).
Adding coverage for these behaviours can increase confidence when we introduce
internal hasbits to help with presence tracking for implicit presence fields.
mutable_foo will in general set the hasbit, so the generated code will need to
check that field is nonempty before serializing.

Before all invocations would try to create a library called protobuf_codegen_upb_gen_code. Now it should properly use the name of the crate currently being built.

This should save a little memory. We've observed hundreds of such empty arrays
in some applications.
This affects non-empty messages with none of:
- repeated fields
- map fields
- fields to check if they're initialized
