This helps push for comparing against nullptr more consistently.
Also replaces .Get() == nullptr and .Get() != nullptr with just ==
nullptr and != nullptr.

This makes refcounting of these objects more automatic to try and
prevent leaks or use-after-frees in the future.
Also removes operator* from RefBase (and Ref) because it is never used
and cannot work in a normal way for ObjectiveC protocols that cannot be
dereferenced.

This will allow using the same logic for other kinds of smartpointers,
like NSRef<>

Previous to this change, you were unable to assign or move Ref<Derived>
to a Ref<Base>.
This change addresses the problem by introducing <typename U> versions
of assignment, copy and move methods. nullptr_t specific ones were
also added to disambiguate things for the compiler.

- Move RefCounted to common (from dawn_native) so that we can use
it from additional places.
- Use EXPECT_ macros instead of ASSERT_ in RefCounted tests for
improved logging on failures.
- Add a missing test for Ref::Detach.
- Plug memory leak in RaceOnReferenceRelease

This changes RefCounted to increment and decrement the refcount by steps
of 2, so that a 1 bit payload can be inlined in the refcount. This
avoids using a whole boolean + padding (4 or 8 bytes in general) to know
if objects are errors.
Fixes a longstanding optimization TODO.

PipelineLayout was re-entering in NXT to create the default empty BGLs,
but forgot to remove the initial external refcount for them.
Fixing this showed an issue where it was impossible to externally
reference a RefCounted that had only internal references, fix this as
well and add a test.
This directory used to contain both the state tracking code for the
backends, and the common utilities that could be used both by the
backends and the rest of the code. Things are now:
- src/common is utility code for the whole repo
- src/backend contains libNXT's code
- src/utils is utility code that we don't want in libNXT
This commit also changes all includes to use global paths from src/
bacause it had to touch a bunch of #include statements anyway.
