[Piglit] [PATCH 14/18] shader_runner: Add texture storage command.

[Francisco Jerez]

"texture storage <texture index> <texture target> <format> (<levels>
 <dimension>...)" calls the corresponding glTexStorageND command on a
newly allocated texture object, where N is determined based on the
number of dimensions passed as argument.
