This enables depth-stencil textures to track per aspect state
independently. It lifts the restriction that depth and stencil
store ops must be the same as they now have independent clear
states. It will also enable correct barriers on Vulkan and D3D12.

Format::aspect should be a mask so that it is easier to iterate over
and test if an aspect is present.
This CL also re-exports wgpu's EnumClassBitMask helpers in dawn_native.
It also adds an EnumMaskIterator which wraps BitSetIterator to allow
iterating over the enums in an enum mask.
