We had _upb_Message_New(), which created a message from a mini table and was
being used outside of upb even though it is an internal-only function.
We also had upb_Message_New(), which created a message from a message def.
Now there is a single public function, upb_Message_New(), which creates a
message from a mini table and covers all use cases. (The internal version has the same definition and is used for inlining.)

1. upb now tolerates a present-but-empty package name in a `FileDescriptorProto`.
2. upb now always returns a non-NULL string for `upb_FileDef_Package()`. If the package was empty or missing, the returned string is zero-length. This better matches the proto2 behavior: `proto2::FileDescriptor::package()` always returns a package string, which may be empty.

The previous change did not have the desired effect, because the generated code uses the class named "Message" instead of "CMessage."
There was no real need to use the class "CMessage" instead of "Message." The new name is simpler and will make the previous change work.
