Derive storage bindings via naga::StorageAccess instead of naga::GlobalUse

[teoxoy]

Resolves #3983.

Changes

• Derive storage bindings via naga::StorageAccess instead of naga::GlobalUse.
• Removes the feature check for read-only and read-write storage textures as it's later checked by create_bind_group_layout.

  	match access {
  	wgt::StorageTextureAccess::ReadOnly
  	| wgt::StorageTextureAccess::ReadWrite
  	if !self.features.contains(
  	wgt::Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES,
  	) =>
  	{
  	return Err(binding_model::CreateBindGroupLayoutError::Entry {
  	binding: entry.binding,
  	error: binding_model::BindGroupLayoutEntryError::StorageTextureReadWrite,
  	});
  	}
  	_ => (),
  	}

• Also removes the GlobalUse checks from check_binding_use as naga is already checking those.

I'll take this as a reviewer! I might not be able to do it until my tomorrow morning, but I'll strive to do it before next office hours on the Mozilla side.

LGTM (noting that my review is impotent still, according to GH)! It took me some reading, but after getting to #3983 (comment), the changes here clicked for me. It's great that this makes for simpler code, too.
