0e9320b5b5 Use Ref<TextureBase> instead of TextureBase* in more places
To avoid accidental memory leaks on account of using raw pointers,
use Ref<TextureBase> as method return type except at Dawn interface
boundaries.

f204cf2c4f Add Ref<T> specialization for Result
Ref<T> specialization will allow us to, in a future change, return
Result<Ref<T>> instances from Create methods while still keeping the
tagged pointer optimization.

69c68d01b2 Improve Memory Management of Result class
The way in which the Result class is used in Dawn can be fragile
with respect to memory management because the caller of AcquireError
must know they need to delete the returned pointer or a memory leak
will occur. We've had a couple of instances where developers have
accidentally left out the delete call and managed to get past code
review.

This CL changes the Result class so that it assumes the error is
allocated on the heap and forces the caller to use unique_ptr when
calling AcquireError.

bd481fc199 Allow ResultOrError to downcast from backend to frontend types
More concretely this makes Result<T*, E*> able to be move-constructed
from Result<ChildClassOfT*, E*> for free.

d6cc1fe099 Add an implementation of Result<const T*, E*>
The existing implementation of Result with tagged pointers was not able
to handle constant pointers for the result. This is required in
follow-up CLs to return internal formats in a ResultOrError.

This CL extracts the tagged pointer logic out of Result<T*, E*> so it
can be shared with Result<const T*, E*>.

Tests are also added to cover Result<const T*, E*>.

90e594ee8b OpenGL: Implement the backend connection and adapter.
The OpenGL backend can't gather discover default adapters because it
needs getProc to do anything so we add DiscoverAdapters method to
Instance that takes backend-specific options.

dawn_native::opengl::CreateDevice is removed in favor of the adapter
path so OpenGLBinding is modified to create an instance locally. This is
only temporary until all backends support adapters, at which point a lot
of *Binding code will be factored.

Also contains a small fix for Result<T, E> with movable types.

df72914a60 Result: Add default template for Result<T, E>
It currently is a tagged pair instead of a tagged union because it was
much easier to write and the optimization can come later.

44b5ca4aa1 Add a functional-y Result<T, E> class and tests for it.
Implements two optimized versions of Result, one for Result<void, E*> as
a nullable pointer, and one for Result<T*, E*> as a tagged pointer.
