Corentin Wallez e8316538e3 Normalize case X : {} break; to case X : { break;}
Dawn was using a very uncommon way to do breaks from case statements
when a block was introduced for that case statement. Fix it by running
the following commands:

  git grep -l "} break;" | xargs sed -i "" -e "s/} break;/break;}/"
  git cl format

Some -Wunreachable-code-break become very apparent in this CL but and are
fixed in a follow-up to keep mechanical and manual changes separate.

Corentin Wallez 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.

Corentin Wallez 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).
