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.

This commit adds utils::MakeBindGroup to make code craeting bind groups
nicer to read. Additional tests are added that give 100% coverage of
ValidateBindGroupDescriptor.

ObjectBase will contain data that all WebGPU objects have such as a
pointer back to the device, a refcount (via inheriting from RefCounted),
a name, an error status etc.

Resources used to have both a current and an allowed usage but the
concept of current usage has been removed so we can rename "allowed
usage" to "usage" to make the name match WebGPU's
WebGPUBufferDescriptor::usage and WebGPUTextureDescriptor::usage

BindGroup usage isn't something that's part of WebGPU's sketch.idl and
it might never exist. Remove it to simplify the migration of bindgroup
to descriptor.
