This also introduces a per-aspect supportedComponentTypes that exactly
mirrors baseType for now but will contain additional bits in the future
(like DepthComparison for depth textures).
It is also a step towards being able to create single-aspect view of
depth-stencil textures to sample either the depth or the stencil
component.

Previously Format::Type was used instead of wgpu::TextureComponentType
so that ::Other could server as a tag value. This was confusing and
almost the single use of ::Other.
In a follow-up CL the format baseType is changed to be a per-aspect
value, and Format::Type. This CL is a self-contained step in that
direction.

A lot of our switches over enum values use the following pattern:
default:
UNREACHABLE();
return foo;
This is problematic because when adding a new value to one of the WebGPU
enums, there is no compilation error for switches that are missing it.
Currently we're supposed to write code and tests and fix UNREACHABLEs when
we see them.
Instead we should strive to have most switches on enums to be complete
and explicitily tag unreachable values as UNREACHABLE. Some switches
might still want to use default: UNREACHABLE() if only a couple values
need to be handled out of very many.
In this CL we go through all the UNRAECHABLEs and change them if need
be. Also an ErrorQueue class is added to avoid having
QueueBase::SubmitImpl just be UNREACHABLE (and force overriding
instead).

This CL adds a TypedInteger helper which provides additional type
safety in Dawn. It is a compile-time restriction that prevents integers
of different types from being used interchangably in Debug builds.
It also adds ityp::{array,bitset,span} as helper classes to wrap std::
versions (not span). These accept a template paramter as the Index type
so that typed integers, or enum classes, may be used as a type-safe
index.
For now, bind group layout binding indices use TypedInteger. Future
CLs will convert other indices to be type-safe as well.

Allows bindgroups that use the same samplers to share
a descriptor heap allocation. This is particularly important
for sampler heaps which incur expensive pipeline flushes
due to the smaller size requiring more frequent switches.
The device dolls out entries to a sampler heap allocation cache.
When the BindGroup is created, it does a lookup and refs the
allocation. This ensures the cache does not grow unbounded
or needlessly store unused entires.
This change is a follow-up of de-coupling heaps.

This patch adds all the validations on the creation of bind groups with

1. Only the textures with STORAGE usage can be used as read-only or
write-only storage textures.
2. The format of the texture view used as read-only or write-only
storage texture must match the corresponding declarations in the

3. The texture view dimension of the texture view used as read-only or
write-only storage texture must match the corresponding declaration
in the bind group layout.
Note that we don't test the match of the sample count because currently
we don't support sample count > 1 when creating a texture with STORAGE
usage and creating a bind group layout with read-only or write-only
storage textrue binding type.
This patch also adds a unit test to verify that it is invalid to create

binding type and dynamic offsets.
This patch also implements the bind group with storage textures on

In a typical application, most draws will use different uniforms values for
things like the world position and orientation. In the current state of WebGPU
this means that a new bind group needs to be created for each draw to set the
right uniforms. Bind group creation is expected to be more expensive than
recording draws because they incur an allocation.
This feature is to reduce the number of bind groups that need to be

Dawn used to return "nullptr" when an error happened while creating an
object. To match WebGPU we want to return valid pointers but to "error"
objects.
This commit implements WebGPU error handling for all "descriptorized"
objects and changes the nullptr error checks into "ValidateObject"
checks. This method is used both to check that the object isn't an
error, but also that all objects in a function call are from the same
device.
New validation is added to objects with methods (apart from Device) so
they check they aren't error objects.
A large number of ASSERTs were added to check that frontend objects
aren't accessed when they are errors, so that missing validation would
hit the asserts instead of crashing randomly.
The bind group validation tests were modified to test the behavior with
both nullptrs and error objects.
Future commits will change the CommandBufferBuilder to not be a builder
anymore but an "Encoder" instead with special-cased error handling. Then
once all objects are descriptorized, the notion of builders will be
removed from the code.

The fuzzer is able to trigger nullptr reads by failing to create objects
and then using the resulting nullptr in other operations. The proper fix
is to implement WebGPU error handling where creation failure returns a
valid but "error" object.
However implementing this error handling is a lot of work, so in the
meantime we use nullptr checks in relevant places to fix the fuzzer
issue. These checks will be removed once the error handling is changed.
