mesa: Define helper function to get the number of texture layers.
And to check if it can have layers at all. This will be used by the
implementation of ARB_shader_image_load_store.
v2: Fix constness of texobj argument, use assert and return reasonable
default rather than calling unreachable() in default switch case.
