Support Storage Textures as Valid Binding Types

This patch adds the basic validation of read-only storage texture,
write-only storage texture and read-write storage texture as new
binding types with no bind group layout provided in the creation of
pipeline state objects.

- Read-only storage textures can be used in vertex, fragment and
  compute shaders.
- Write-only storage textures can only be used in compute shaders
  due to the limitation on Metal.
- Read-write storage textures are not allowed now and they are
  reserved to be supported as an extension in the future.
