Joe Tsai 387873dd53 all: implement support for proto3 optional semantics
In the upcoming 3.12.x release of protoc, the proto3 language will be
amended to support true presence for scalars. This CL adds support
to both the generator and runtime to support these semantics.

Newly added public API:
	protogen.Plugin.SupportedFeatures
	protoreflect.FieldDescriptor.HasPresence
	protoreflect.FieldDescriptor.HasOptionalKeyword
	protoreflect.OneofDescriptor.IsSynthetic
