Instead of counting descriptors to be allocated for the entire command
buffer in a pre-pass, the bindgroup state tracker is used to allocate
only dirty bindgroups upon recording draw/dispatch. If the heap has no
more room and must be changed, bindgroups will be re-created according
to the BGL.
A future change will address the CPU descriptors and removal of the
pre-pass.

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.

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.

This patch implements "store and MSAA resolve" store operation on Metal

a workaround that does MSAA resolve in another render pass.
Driver workaround is one type of Dawn Toggles. Dawn Toggles will include
other optional optimizations and features that can be configured to use
or not when we create Dawn Devices.
As all Metal try bots don't need this toggle, to better test this
patch on the try bots:
1. We add the support of forcing enabling a workaround when starting an
Dawn end2end test so that we can test the workaround on the platforms
where the workaround is disabled.
2. We add an optional parameter DeviceDescriptor to CreateDevice() so
that we can custom the toggles the Dawn device should use.
This patch also adds the support of querying toggle details from Instance
