These still had vestiges of HLSL.

As the resolver currently enforces in-order declarations, this does not
change the declaration order from iterating over the
ast::Module::GlobalDeclarations.
The MSL backend has been changed to use the
sem::Module::DependencyOrderedDeclarations list instead of looping over
different declaration types separately.

Other shader types don't need this.
Also fix code style of member var.

This is not 100% correct (the exceptions for mat2 and friends are not
implemented yet), but gets more tests passing in Dawn.

The MSL headers have annotations that requires that the lod for 1D
textures is a constexpr with value 0. This affects .get_width() and
.read().

The CombineSamplers transform was incorrectly flagging StorageTexture
(which in GLSL ends up as image2D) as needing to be combined with a
sampler, or at least renamed. This is incorrect: StorageTexture never
has an associated sampler, so don't try to pair it up and just output
it as image* in GLSL.
In GLSL, textureLoad (aka texelFetch) of depth textures is not allowed.
The fix is to bind the depth texture as the corresponding f32 texture
instead (e.g., texture_depth_2d -> texture_2d<f32>,
texture_depth_cube -> texture_cube<f32>, etc). This requires changing
both the uniform globals and function parameter types. We're now going
to receive a vec4 instead of a float from texelFetch, so add a ".x"
member accessor to retrieve the first component. (Note that we don't
do this inside a CallStatement since this gives the CloneContext
indigestion, and CallStatement is going to ignore the result of the
call anyway.)
We were failing to find the dummy samplers that Dawn creates for the
calls that actually do require a dummy sampler, since the old Inspector
implementation of GetSamplerTextureUses() does not find them. The fix
is to implement a new Inspector call to return the texture/sampler
pairs the Resolver found during resolution. This will include the
dummy sampler as a null variable pointer.
In order to identify the placeholder sampler, we pass in a BindingPair
to represent it. When we discover a null sampler in the variable pair,
we return the passed-in placeholder binding point to the caller (Dawn).
(Dawn will use a group of kMaxBindGroups, to ensure that it never
collides with an existing sampler.)
