EnableIfHpbClass was too restrictive in the past; it was
toggled only if <T> was extended. This has been rectified
to toggle if T extends T::Access, which reflects the
true intention.

At the moment, hpb's public api solely returns Ptr<const Extension>. We'd like to support all non-msg types like int32, int64, bool etc.
These should not return a Ptr<...> but the underlying primitive itself.
We start by adding support for int32 and int64.

Have ExtensionIdentifier have a upb_MiniTableExtension* instead of subclassing a class that is just a plain holder for a upb_MiniTableExtension* with a getter with the same name
We generally want to lean toward composition over inheritance. Without a compelling reason for inheritance, let's prefer composition for clarity, flexibility, and evolvability. Locking oneself into an inheritance hierarchy has marred many a codebase.

Move hpb::internal::{Serialize, HasExtensionOrUnknown, GetOrPromoteExtension, DeepCopy, DeepClone} to message_lock.h as they all use the message lock
absl status helpers are now housed in status.h

```
hpb::Arena arena;
auto foo = hpb::CreateMessage<Foo>(arena);
foo.GetInternalArena(); // this call will now be impossible
```
Before this CL, any Proxy/Ptr could get its internal arena. This
unnecessarily leaks upb internals when they should be
interacted with via hpb::interop::upb::*.

This also increases compliance by adding `default_applicable_licenses` to several `BUILD` files that previously did not have it.

This CL is mostly a no-op, except that now google3-only code is actually stripped from OSS, instead of being preserved in `# begin:google_only` blocks.
This follows the conventions of the greater Copybara ecosystem.

This simplifies upb by removing differences between google3 and OSS.
This also points upb at the protobuf license, instead of keeping a separate copy around for upb.
