This is in preparation for a change that will change all the
CreateFooInternal to be CreateFoo so they can be called in a
reentrant manner without special refcounting.
This also standardizes all the backends (except OpenGL and Null)
to use Object::Create that returns a Ref<T> or ResultOrError<Ref<T>>,
something we wanted to do for a long time.

kMaxBindingsPerGroup is not a real WebGPU limit. Code in Dawn that
uses it now uses dynamically sized vectors, optimistic stack_vecs or
a different limit like kMaxDynamicBuffersPerPipelineLayout.
The CL introduces kMaxOptimalBindingsPerGroup=32 which is used to size
the static portion of stack_vecs, but the value is tentative.

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.

Move the CPU descriptor allocators to the device and bucket them to
ensure only kMaxBindingsPerGroup exist rather than create them per BGL.
Also, renames NonShaderVisible => Staging.

Note: Adds validation to ensure binding size > 0.

RefCounted (and derived) destructors should be protected on the class
to ensure the objects can ONLY be destructed by calling Release. This
avoids errors cause by destroying objects out from under code which
has an active reference count.
Unfortunately, many of the 'base' classes must continue having public
destructors because they are used as "blueprint" objects created on
the stack.
Added final on most-derived classes.
Ideas for future improvement:
- Change "base" objects to have protected destructors but create new
blueprint objects that privately derive from base objects. This
limits the blueprint object's usefulness to only be a blueprint.
- Modify createX methods to return Ref<Object> instead of Object*

The dawn.h and dawncpp.h structure definitions references dawnFoo or
dawn::Foo respectively when it should reference dawn_native::FooBase* in
dawn_native. Autogenerate files to declare the dawn_native version of
the structs and change the ProcTable generation to use it instead.
This is important to make libdawn_native a shared library because
currently it was depending on dawncpp's definition of .Get().
