Refactors the existing general reflection code to either use Tint or
SPIRV-Cross, depending on the backend being used and provided flags.
Tint is used when UseTintGenerator is enabled, otherwise SPIRV-Cross is
used.
For OpenGL, when Tint is used, additional reflection is performed using
SPIRV-Cross to support GLSL generation.
There still exists backend specific reflection that needs to be
implemented in Tint for the complete removal of SPIRV-Cross for
non-OpenGL when UseTintGenerator is enabled.

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.

Turns on Tint generation of SPIR-V if UseTintGenerator is on.
This affects SPIR-V generation for Vulkan, and SPIR-V passed
into SPIRV-Cross to produce GLSL.
It enables DrawTests use_tint_generator for Vulkan/GL where it
should have at least basic support.

This factors code to move parsing of tint::ast::Module to the
frontend. All backends will use this code path when
UseTintGenerator is enabled for both SPIR-V and WGSL ingestion.
To avoid too much code explosion, parsing and validating the
shader is moved into ValidateShaderModuleDescriptor which
returns a result struct that gets passed into creation.

In WGSL, textureLoad translates to an OpImageFetch without the
combined sampler. In OpenGL, we need to use SPIRV-Cross to insert
a dummy nearest filtering sampler and bind that in the backend.

OpenGL ES doesn't have the glShaderStorageBlockBinding() call, so we
modify the binding decorations set in the shader instead. This requires
plumbing through some more pipeline state at shader translation time.

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.

Also fix a couple style and formatting issues.

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*

This completely removes the dependency on glad by generating the GL
headers from gl.xml directly.
This requires adding khrplatform.h so all Khronos dependencies are
gathered in third_party/khronos.
Also removes a stray CMakeLists.txt that was still hanging out.
