These types are effectively two ways to spell the same type, but MapView/MapMut is more terse, especially where the unnamed lifetime was used which can now be implied (`View<'_, Map<K, V>>` can just be `MapView<K,V>`)

`absl::string_view`.
This is a modernization of the API and performance improvement for all callers.
Currently gated behind opt-in macro
`PROTOBUF_TEMPORARY_ENABLE_STRING_VIEW_RETURN_TYPE` for users to test and prevent
issues when the breaking change happens.

These are very old unit-tests that appear to have been written to provide some conformance and fuzzing capabilities before we had more comprehensive solutions. Today, they should be already covered by our conformance tests and fuzz tests and create unnecessary noise.
The goal of this change is to remove the checked-in binary golden data that we no longer know how to regenerate. There is a lot of nearby code that could likely also be cleaned up in a follow-up

We were really inconsistent on where we put Private or not and this tries to make a sensible consistent state of:
- For types that are exposed to application code, any pub methods which are only pub so they can be used by gencode (which is mostly anything that has any internal/runtime type anywhere on the parameters or return type list), have those methods have both a `Private` arg and doc(hidden)
- For structs that are only inside __runtime / __internal to begin with, put doc(hidden) on the types, and don't put Private on any of their methods since callers can't reach those types regardless.
Note that for exposed functions which also _accept_ another internal/runtime type in a parameter, the additional `Private` arg is superfluous since application code shouldn't ever be able to reach one of those internal types to be able to pass one in, but this keeps the pattern of keeping Private on it in those cases as well (the `Private` would still be the only guard on methods which only _return_ an internal type).

This ensures the names of these jobs will properly be prefixed with "[SKIPPED] (Continuous)" and will show as passed instead of skipped.

Putting it into BUILD files unintentionally forces it on all our downstream users. Instead, we just want to enable this during testing and let them choose for themselves in their builds.
Note, that this expands the scope of -Werror to our entire repo for CI, so a bunch of fixes and opt-outs had to be applied to get this change passing.

This is useful/necessary when the caller wants to tie the View to a lifetime other than a stack frame, including 'static.
The documentation is clarified that the preexisting one should be preferred in most situations, and only use the new one where tying the View lifetime to a stack frame isn't suitable.

3.x.x descriptor.proto generated code is *not* supported with 4.x.x runtime, since this results in an ODR violation with the descriptor.proto built into the 4.x.x runtime. This is expected to result in undefined behavior / failures.
Tested against //java/core:v25_generated_message_test_jar (binary compatibility) and //java/core:v25_generated_message_test_srcjar (source compatibility)

This should get use feedback so we know if usage, the intent is to
be able to remove the different generation code in the future if
folks don't need these.

Protobuf enums in C++ always have `int` as their backing type, so for the
purpose of use as a map value, we can just treat enums as 32-bit ints. This
allows us to delete the enum-specific generated C++ thunks.

This change adds delete, clear, serialize, parse, copy_from, and merge_from
operations to the runtime. Since these operations can all be implemented easily
on the `MessageLite` interface, we can use a common implementation in the
runtime instead of generating per-message thunks for all of these.
I suspect this will also make it possible to remove some of our generated trait
implementations and replace them with blanket implementations, but I will leave
that for a future change.

Migrate ::hpb::internal::GetMiniTable to ::hpb::interop::upb::GetMiniTable
hpb.h now shows signs of backend-awareness, #including upb.h if the backend is known to be upb. If no backend is picked, we error out at this time since we solely support upb.
ClearMessage has been migrated to backend-aware hpb.

We can use memset for zero initialized objects, and memcpy for ones cloned from the prototype.
This permits creating objects from the parser without calling virtual functions.
For the cases where the efficient implementation can't be used, we generate a "placement new" style function to offload the memory allocation out of the code generation. This reduces code bloat even when we can't use the more efficient implementation.
Migrate many callers of `New` and similar to the new functionality. In particular, the parsing paths will use this.
Finally, make `New` non-virtual now that `MessageLite` can handle it directly. It reduces binary size.
