Implement creating and using 1D texture views. 

- Adds a test to sample a 1D texture.
 - Adds a test writing to a 1D texture as a storage texture.
 - Reworks some of the StorageTextureTests helper code to allow passing
   custom sizes (since 1D textures must have height=1).
 - Deletes some dead code leftover from readonly storage textures.
 - Adds validation tests for 1D texture view creation.
