ValidateOrSetAttachmentSize() was asserting that
textureSize.width >> attachment->GetBaseMipLevel() is nonzero.
This is not true for rectangular textures, where the smaller dimension
may hit the lower bound and must be be clamped at 1.
Fixed by calling GetMipLevelVirtualSize() which performs the clamp.
Added a test which exercises rectangular mipmapped textures as color
attachments. This required a few fixes to the test harness, which had
the same bug as that fixed in the code (assumes (width >> size) > 0).

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.

This patch fixes the issues on the initialization of buffers with
MapRead usage and mappedAtCreation == true.
1. The buffers with MapRead usage and mappedAtCreation == true can be
read from the CPU side just after the creation of the buffer,
however at that time the internal pending command buffers may not
be executed, thus causing the buffer is not cleared as is expected.
2. On D3D12 the buffer with MapRead and mappedAtCreation == true is
created on the READBACK heap, so all the data written in the CPU
side cannot be uploaded to the GPU memory. When the buffer is mapped
again all the original data written through the CPU pointer will be
overwritten by the data in the GPU memory (which means it is also
cleared to 0).
This patch fixes this issue by:
1. clearing the buffers with mappedAtCreation == true on the CPU side.
2. on D3D12 making the buffer with MapRead and mappedAtCreation == true
use the staging buffer instead of mapping itself.
Note that this change is only related to the code path with Toggle
"nonzero_clear_resources_on_creation_for_testing" enabled, currently
we don't plan to do the similar change when we enable Dawn wire.

Because OpenGL default to GL_CCW (which with the Y-flip is the inverse
of wgpu::FrontFace::CCW that's default in the descriptor), if
stencilFront != stencilBack and cull mode is none, then the incorrect
stencil face descriptor was used.
