Vulkan allows them, but WGSL does not.
A duplicate decoration is purely redundant.
A parameterized decoratio with different parameterization is
an inconsistency and a semantic error, at least for currently defined
SPIR-V decorations.
So for each target, only take the first decoration of each kind.

FXC fails to compile code that assigns to dynamically-indexed fixed-size
arrays in structs on internal shader variables with:
error X3500: array reference cannot be used as an l-value; not natively
addressable
This CL detects this case, and transforms such assignments into copying
out the array to a local variable, assigning to that local, and then
copying the array back.
Also manually regenerate SKIPs for HLSL/FXC after this change, which
fixes 30 tests. Also exposes some "compilation aborted unexpectedly" now
that "array reference cannot be used as an l-value" has been fixed. For
tests that fail for both DXC and FXC, updating SKIPs to the DXC one to
help distinguish actual FXC bugs from valid errors.

It requires to revise quite a few flags in order to implement
readonly depth/stencil attachment on Vulkan. For example:
- VkAccessFlags,
- VkPipelineStageFlags,
- VkImageUsageFlags,
- and the most important: VkImageLayout.
These revised flags need to be applied to many Vulkan objects.
For examples:
- VkImageMemoryBarriers,
- IMAGE_LAYOUT revisions in descriptor set (bindings),
render pass, and subpass,
- and loadOp/storeOp revisions in render pass and subpass.
This change also does some workarounds in order to make Vulkan
validation layers happy. For example:
- use DEPTH_STENCIL_READ_ONLY image layout for binding a
depth/stencil texture,
- add DEPTH_STENCIL_ATTACHMENT_BIT image usage for binding a
depth/stencil texture.
Note that STORE_OP_STORE is used for depth/stencil's storeOp for
readonly attachment. It leads to Vulkan validation error. This
change igores that error and let it proceeds and it works well.

Bug was a result of an external BGL reference that lingered after device was destroyed leading to a bad read on the device's FencedDeleter when the BGL reference was finally released. Fix just makes sure that the previous code path runs during the device destruction instead of afterwards.
- Removes passthrough call in BGL to the allocator and instead has the device keep track of the allocator directly so that the list can be used to both deallocate bind groups and bind group layouts at the end.
- Makes the allocator an ObjectBase so that we can have an explicit copy of the device since getting it from the layout can be dangerous now that the allocator may outlive the layout.

Migrate some of the validation logic over to use the results of behavior
analysis.
The most significant changes are:
* Unreachable-statements now consider merge-points of control flow. For
example, if all branches of a if-statement or switch-statement either
return or discard, the next statement will be considered unreachable.
* Unreachable statements are no longer an error, but a warning. See
https://github.com/gpuweb/gpuweb/issues/2378.
* Statements that follow a loops that does not break, or have a
conditional will now be considered unreachable.
* Unreachable statements produced by the SPIR-V reader are now removed
using the new RemoveUnreachableStatements transform.
Some other new changes include additional validation for the continuing
block for for-loops, to match the rules of a loop continuing block.
The new cases this validation is testing for are not expressible in
WGSL, but some transforms may produce complex continuing statements that
might violate these rules. All the writers are able to decay these
complex for-loop continuing statements to regular loops.
