This change adds test runs for GCC, Windows, and Mac. The 32-bit ASAN test
turned out to be somewhat difficult to migrate, so I left a TODO for that one.
I made sure to give each build environment its own cache prefix, so that we
don't end up with artifacts built by different toolchains conflicting with each
other in the same cache.

1. getter function to access the upb_Map corresponding to a map proto field
2. conversion function to get a Go map from a upb_Map. The conversion function uses generics, so it must be a standalone function independent of `MessageAccessor`.
Accessing map fields is not as efficient as accessing other proto field types, because of two reasons:
- we need to make a copy of map values in Go, since the memory representations are different in UPB C
- we need to call C functions from Go, because the upb_Map struct fields are not exported and we can't access the bits directly, causing performance overhead
Luckily the map fields can be quite rare, so the performance overhead should not be too significant overall.

The issue is that if another component (MediaPipe in this case) calls PackFrom, there'll be linker errors because kTypeGoogleApisComPrefix wasn't found.

The Python comparison protocol requires that if an object doesn't know how to
compare itself to an object of a different type, it returns NotImplemented
rather than False. The interpreter will then try performing the comparison using
the other operand. This translates, for protos, to:
If a proto message doesn't know how to compare itself to an object of
non-message type, it returns NotImplemented. This way, the interpreter will then
try performing the comparison using the comparison methods of the other object,
which may know how to compare itself to a message. If not, then Python will
return the combined result (e.g., if both objects don't know how to perform
__eq__, then the equality operator `==` return false).
This change allows one to compare a proto with custom matchers such as mock.ANY
that the message doesn't know how to compare to, regardless of whether
mock.ANY is on the right-hand side or left-hand side of the equality (prior to
this change, it only worked with mock.ANY on the left-hand side).

Remove message/message.h as a hdr from :message_internal
Lock down the visibility of :message_types to upb-only
message/types.h is not an internal header because the definitions there are part of the public surface. But the fact that it needs to exist is an implementation detail that should remain opaque, so make it a private dep.

This new option will cause only the files that provide types to
be imported into the generated code. This helps reduce the inputs
that aren't needed (folks ignoring the protoc warnings) and for
things imported only for custom options as the objc generated code
doesn't capture those and thus the imports aren't needed in the
generated code.
Also do some general import cleanups.

Implementing this method allows descriptors to be used in contexts that support
ABSL's formatting, most notably gunit's PrintToString and absl's StrFormat. The
implementations are done on the concrete descriptor type, which appears to be more
idiomatic for AbslStringify. Implementing them on pointers-to-descriptors would be
nicer for users who typically interact with pointers, but that would conflict with
AbslStringify's built-in support for pointers.
The implementation simply forwards to DebugString for simplicity.

Arena enabled copy construction provides efficiency gains for the rather common construct where a message is currently copied by first creating a default initialized instance through the regular (arena) constructor, and then recursively filled from the source message using 'MergeFrom' or 'CopyFrom'.
Arena enabled copy construction is feature gated in port_def.inc and currently not enabled by default.

It ended up being odd to construct the AccessorGenerators ahead of time given some specific Context<>: since each of the three methods on AccessorGenerators demands a different Context than the initial one so they shouldn't hold that Context anyway. It ended up just being a spooky parallel array to the Fields with an unenforced invariant that all methods would be called with a new Context<> but the same underlying FieldDescriptor later.

The new naming will use our new vocabulary, and restrict feature access:
Unresolved source features - source-retention features that generators need to validate their own features. These should not be sent to the runtime or used for any decision-making.
Resolved source features - fully resolved source-retention features. These should be used to make codegen decisions, but shouldn't be sent to runtimes.

This is a no-op change. Since Copybara will automatically format PRs with ClangFormat, this can lead to spurious changes that make CLs harder to review, as in cl/549058046. To avoid this, we format everything with clang-format in a single no-op change.
This CL also forces all pointer alignment to left pointers, for consistency (clang-format would normally deduce based on existing style in each file).
Also added `// clang-format off` comments in some places where PHP conventions lead to badly formatted code.

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)

Lock down the visibility of :wire_internal to upb-only
Merge :mini_descriptor_encode_internal into :mini_descriptor_internal

There are still a bunch more test runs to migrate, but this change adds a few
more that were unblocked by the `exclude-targets` flag.

This allows the compiler to statically detect use-after-free bugs.
This change touches a subset of field types. More changes to follow.

My editor reformatted this file to add a missing newline, and this ended up
breaking the test. The added newline caused there to be a newline in the middle
of the Bazel command. So this change adds the missing newline and fixes up the
Bazel command by using the `>-` syntax to treat this as a multiline string
without adding any newlines.

This version is a light-weight, inlined version implemented in terms of `MergeFrom` that extends the protocol buffer API with arena enabled copy construction, but without any explicit (optimized) implementation.
Going forward the protocol compiler will provide an optimized implementation that is expected to save a non trivial amount of compute.

Since protoc can't know the full set of features that matter to a plugin, sending partially resolved features is unnecessarily confusing. Plugins written in C++ will have automatic access to the fully resolved features via previous enhancements. Plugins written in other languages will need to reimplement feature resolution logic. Future changes will document this algorithm and provide conformance testing.
