7e8385c183 Move and improve RefCounted
- 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

c64242d4c2 Make RefCounted derived objects have private destructors
RefCounted (and derived) destructors should be protected on the class
to ensure the objects can ONLY be destructed by calling Release. This
avoids errors cause by destroying objects out from under code which
has an active reference count.

Unfortunately, many of the 'base' classes must continue having public
destructors because they are used as "blueprint" objects created on
the stack.

Added final on most-derived classes.

Ideas for future improvement:
- Change "base" objects to have protected destructors but create new
blueprint objects that privately derive from base objects. This
limits the blueprint object's usefulness to only be a blueprint.
- Modify createX methods to return Ref<Object> instead of Object*

d26ee85fba Implement the webgpu.h swapchains in the frontend and Null backend.
The state-tracking of the webgpu.h swapchain is a bit complicated
because contrary to implementation-based swapchains, they have more
guarantees and a "replacing mechanism". For example instead of hoping
the implementation-based swapchain resize automatically, the
surface-based swapchain needs to be replaced by a new swapchain and
invalidated.

This mechanism of invalidation also needs to be triggered when the last
reference to the surface is lost because we don't want to risk the
application destroying the window from under us.

Adds tests for all the cases of invalidation I could think of apart from
device loss.

3a1746e71c Introduce wgpu::Surface and implement it for HWND, X11 and Metal
This is another step to implement webgpu.h swapchains, Surface is
essentially a union type of all the types of windows that can be used to
create swapchains.

Changes to allow implementing wgpu::Surface and test its creation are:

 - Add GLFWUtils.cpp/.h/_metal.mm  that contains helpers used to use
WebGPU with GLFW. This deprecates BackendBinding.h that will be removed
when the NXT swapchain is removed.
 - Add a `dawn_use_x11` GN variable to factor all the places in BUILD.gn
where we checked whether we should use X11.
 - Add a `supports_glfw_for_windowing` GN variable in the main BUILD.gn
file to control which configuration tests and samples using GLFW can be
built.
 - Add a ObjCUtils.h to contain some ObjC functionality that we'd need
in files that otherwise would be C++ (so that they can be compiled on
all platforms).
