GLSL: fix textureLoad() and textureStore(), depth textures, and more. 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.)
