Add the webgpu.h swapchain creation path
This commit changes wgpu::Device::CreateSwapChain to take an additional
wgpu::Surface argument. Passing nullptr is enough to stay on the
previous swapchain implementation, until the new one is ready.
In order to support both the "old" implementation-based swapchains and
the "new" surface-based swapchains. SwapChainBase is now split into
three abstract classes:
- SwapChainBase that has a virtual method for each of the
wgpu::SwapChain methods.
- OldSwapChainBase that corresponds to the implementation-based
swapchains.
- NewSwapChainBase that will contain the surface-based swapchain
implementation and will eventually just be renamed to SwapChainBase.
The interaction of the surface-based swapchains with the Surface objects
aren't implemented yet, neither are the swapchain methods. Only creation
works.
Validation tests for surface-based swapchain creation are added in the
end2end test target because they need to create OS windows.
