When an OpConstantComposite result is used by multiple instructions,
declare it as a module-scope `const` instead of inlining the constant
at each use site. This fixes an issue whereby the spirv-reader was
massively inflating the size of the WGSL it produces, which was caught
via an OOM fuzzer bug.

This prevents us from crashing when a module-scope private variable
has an inferred type that is a built-in struct. We instead fail to
resolve the generated code.

The declaration may be nullptr, so doing this avoids a potential
nullptr deref when the struct is an internal type (e.g. frexp
result). In these cases we will now fail to resolve the resulting
code, which is a little better than just crashing.
A future change will update the resolver to allow us to use the
internal struct names from our transforms.

Whitebox tests call internal functions directly. However, when
implicit device synchronization feature is turned on, some of these
functions will expect that the device is already locked. Thus leading
to assertion failures.
So we need to disable the tests when this feature is turned on.

Normal behavior of ApiObjectBase's APIRelease() which only locks the
device when last ref dropped is not thread safe if the object is cached
as raw pointers by the device. Example of cached objects: bind group
layout, pipeline, sampler, shader module.
The following scenario could happen:
- thread A:
- shaderModuleA.APIRealease()
- shaderModuleA.refCount.Decrement() == true (ref count has reached zero)
- going to call shaderModuleA.LockAndDeleteThis().
- thread B:
- device.CreateShaderModule().
- lock()
- device.GetOrCreateShaderModule()
- shaderModuleA is in the cache, so return it.
- unlock()
- thread A:
- starting to call shaderModuleA.LockAndDeleteThis()
- lock()
- erase shaderModuleA from the cache.
- delete shaderModuleA.
- unlock()
This CL fixes this bug by locking the entire APIRelease() method until
we find a better solution.

> Normal behavior of ApiObjectBase's APIRelease() which only locks the
