This change is a necessary to support workgroupUniformLoad in a
following patch. Otherwise, there is no change to the set of shaders
that are accepted or rejected by the analysis.
We now distinguish between uniformity requirements on the contents of
a pointer parameter versus the pointer value itself when generating
tags for function parameters.
Whilst processing an expression, if we see a sem::Load node we pass a
flag down through child expressions to indicate that we will be
loading from the result. When processing an identifier expression, we
can then select between adding an edge to the source of the
pointer/reference versus the contents of the root identifier that it
corresponds to.
Since the pointers passed to atomic builtins can be uniform, we
special-case them to capture the fact that their return value is
always considered non-uniform.
The arrayLength builtin no longer needs special-casing.
Added many tests to cover various cases that are now captured
differently in the graph. There are two cases that are disabled as
they require variable pointers to trigger the uniformity violation.

Variables declared in for-loop initializers were not being tracked
properly across iterations as a check was wrongly determining them to
be declared inside the loop body.
Also fixes an issue where variables declared in for-loop initializers
were still considered to be in scope after loop exit.

Previously this toggle was implemented only for the Metal backend, but
a need for it was identified on Android as well. This change moves the
implementation to the backend-agnostic command encoder recording so that
it works for all backends. Fundamentally it's still doing the same
thing, however: Swapping resolve targets that point at a non-zero mip
level or layer with a temporary texture and then performing a copy once
the render pass has ended.

Virtual methods are expensive to call, and hashes are frequently tested.
The hash must be immutable, so just calculate it once in the constructor and store it as an immutable field.

The generator_lib.py processing of file renders would check that the
output directory doesn't exist and if needed, would create it. However
by default makedirs errors if the path already exists. This caused
issues when multiple generator_lib.py generators with the same output
dir would run in parallel in builds, because there can be a race where:
- GeneratorA: Check os.path.exists -> returns False
- GeneratorB: Check os.path.exists -> returns False
- GeneratorB: os.makedirs -> Ok
- GeneratorA: os.makedirs -> Exception, fails the build.
Instead use os.makedirs(exist_ok=True) inconditionally to remove this
racy behavior.

to Wire.
Also the commit changes the MapAsync callback firing timing
if pending map buffer is unmapped or destroyed. With this
commit the callback will be fired immediately Unmap or
Destroy is called to match the WebGPU spec. Currently the
callback is fired when the client receives a response from
server but it mismatches the spec.

The resolver now wraps sem::Expression objects with a sem::Load object
anywhere that the load rule is invoked. sem::Expression provides an
`UnwrapLoad()` method that returns the inner expression (or
passthrough, if no load is present), which is analaguous to
Type::UnwrapRef().
The logic for alias analysis in `RegisterLoadIfNeeded` has been folded
into the new `Resolver::Load` method.
Fixed up many transforms and tests. The only difference in output is
for a single SPIR-V backend test, where some IDs have changed due to
slight re-ordering of when expressions are generated.
There may be further clean-ups possible (e.g. removing unnecessary
calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or
transforms that deal with memory accesses), but these can be addressed
in future patches.

2D array texture may corrupt on some Intel devices, making out-of-bound
texture access and memory information leak. It's a critical security
issue. Intel driver team suggested the 24K extra memory approach in
order to mitigate the security issue before.
However, the texture corruption issue (and even the correctness issue)
can be worked around via allocating a few extra layers. And patches
have already been merged in Dawn, with a lot tests for verification. The
24K extra memory for each texture is actually incorrect and unnecessary.
So this patch removes relevant code in Dawn.
This patch mainly reverts some code of this patch below:
