b0d308c9fe [spirv-reader] Emit non-header OpBranchConditional
This emits the equivalent of break-if, break-unless, continue-if,
continue-unless.  But we do it via a regular if-then-else.

Adds a test matrix.
Adds all required tests except for those needing OpSwitch.

bdcd04b1a2 [spirv-reader] Check some merge block dominance
A merge block must be dominated by its own header.
This CL checks the cases where that fails because the
merge block is also the:
- the default or case header for a switch (a different header)
- the true-head, false-head, or premerge-head for an if-selection
  with a different header

db8f804bc3 Reland "Check FP16 support on vulkan backend"
This reverts commit 0357eed7de15e901d14f6149e91bfe03d86958de
and reland commit bdc05c3d5fef780382c3fd5e5ebcb14bd929819a.

The Vulkan-Loader has a bug where if the instance is created
with Vulkan 1.1 and not the promoted extensions, it will skip
emulation and if the ICD doesn't support Vulkan 1.1 nor the
extensions. Enable the promoted extensions, even when creating
a Vulkan 1.1 instance.

Original change's description:
> Check FP16 support on vulkan backend
>
> This patch check FP16 support on vulkan backend, and introduces
> the shader_float16 extension.

e472c459b9 Add validations on the texture-to-texture copies within same texture
This patch adds validations on the texture-to-texture copies within the
same texture to align with the latest change in WebGPU SPEC: When the
source and destination textures are the same one, the source and the
destination subresources involved in the copy must not overlap.

Note that we don't enable the newly added end2end tests on D3D12
because when doing texture-to-texture copy within the same texture, we
need to set the source subresources into TRANSFER_SRC state and set the
destination subresources into TRANSFER_DEST state, while right now we
don't support subresource tracking on D3D12.
