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.

Bug: dawn:269
