This significantly simplifies the internals of PrimitiveMut,
and removes the need to refactor BytesMut and ProtoStrMut
to have the same runtime branching.

Include a comment in the generated header about there being helpers
in GPBWellKnowTypes.h
Generate some extra code for the WKTs that have categories to help
ensure the categories get linked so developers don't have to use
-ObjC in some cases.

We avoid one instruction and the memory access.
Instead of generating:
```
leaq 0xb98201(%rip), %rax
movq %rax, -0x8(%rsp)
```
It now generated just:
```
leaq 0xb981c1(%rip), %rax
```

They should ignore presence and always process key and value.
Remove codegen for methods in MapEntry and use the ones from Message.
Delete dead code in MapTypeHandler.

This change implements maps with keys and values of type string e.g. Map<ProtoStr, i32> and Map<ProtoStr, ProtoStr>.
Implementing the Map type for ProtoStr has been different from scalar types because ProtoStr is an unsized type i.e. its size is not known at compile time. The existing Map implementation assumed sized types in many places. To make unsized types fit into the existing code architecture I have added an associated type 'Value' to the MapWith*KeyOps traits. The associated type needs to be sized and is the type returned by the Map::get(self, key) method e.g. for aProtoStr, the `type Value = &ProtoStr`.

Before this CL, we weren't generating view accessors for messages with depth > 1.
We weren't getting to message::GetterForViewOrMut because we were detecting FieldDescriptor::TYPE_MESSAGE and bailing out.
That check has now been expunged, and we now properly emit the right view, even for messages embedded within messages.
Added tests for:
- another level of submsg access depth
- accessing a message declared outside of the current message (that is, not a direct nested message within the same message)
- accessing the accessor of the accessor of the accessor of a recursively defined message

Collect all static initializers in a single expression at the end of the file.
This reduces code bloat, and provides a way to customize the
registration for weak descriptor messages.

This will allow us to support editions without adding support for proto2 concepts such as closed enums, required fields, and groups. The generator will now only ban unsupported features, meaning that some types of proto2 files will be allowed. The PHP runtime does not yet support editions.

This feature allows for tree shaking within a single .proto file, dropping
unused types while still allowing reflection to work for them via the generated
DescriptorPool.

When unknown fields are discarded using reflection in reflection_ops.cc, unnecessary switching of the internal map representation is triggered.
A map<int,int> field cannot have unknown fields. However, in the current code the check used is
if (field->IsMap() && IsMapValueMessageTyped(field)) {
// Discard map field
} else {
// Discard repeated message field
}
This means that the code proceeds discarding unknown fields for each mapentry using the RepeatedPtrField of MapEntry representation of the map. Causing unnecessary work and unnecessary, potentially big, memory allocation. This PR fixes this.

This is also a bug fix. When a map<int, MyProto> is in a dirty state, previously it would be skipped. After this change it will correctly use the repeated path to clean the MyProto sub-entries

It's up to the user how to set up the threads, but this will allow them to dispatch any recursive work during the descriptor builds to separate threads with their own stack limit.

This is similar to what we did for built-in generators, and gives us the ability to create a new edition without subtley breaking generators that don't support it yet.

- Remove _Internal accessors. They only have one caller and it's better to inline it.
- Remove redundant has bit setting. MergeFrom does it globally instead of per field.
- Reuse existing arena object. Avoids redundant calls to `GetArena()`.
- Use rhs object instead of weak instance for calling `New()`.
- Change repeated fields to use the generic MergeFrom instead of Arena::CopyConstruct.

This is functionally equivalent, but avoids a codegen change under editions where the inherited value of utf8_validation can change for non-string maps.
