This patch fixes a crash issue in both D3D12 and Vulkan backends.
Previously on D3D12 and Vulkan before a compute pass we transitioned
the states of all the resources used in the pass, and before each
dispatch call we only checked if the states of the storage buffers,
read-only storage textures and write-only storage textures need to
be transitioned. This behavior causes two issues:
1. In a compute pass a buffer or texture can be used as both read-only
and writable usages in different dispatch calls (e.g. as storage
buffer in the first dispatch, and as the uniform buffer in the next
dispatch), while this is invalid state combination on D3D12 and isn't
allowed by D3D12 validation layer.
2. In the above case, the state of the buffer is not transitioned into
UNIFORM, which does not match the required state in the next dispatch.
This patch fixes this issue by transitioning all the states in the
current bind group before each dispatch() instead of the beginning
of the compute pass.

The test was failing on Swiftshader, likely because the allocations for
the SSBO and the UBO where neighbors. The UBO test uses uvec4 instead of
uint so it needs 4 times less invocations to perform the test.

If these extern variables are initialized after DAWN_INSTANTIATE_TEST,
they will be zero. Change them to be function calls instead.
Since they're function calls, fold in arguments from ForceToggles to
enable/disable toggles.

This patch extends the BindGroupTracker in the D3D12 and Vulkan backends to
track bound storage buffers. We insert barriers between dispatches to properly
synchronize writes to storage buffers.
