shader/texture: Implement CUBE texture type for TMML and fix arrays 

TMML takes an array argument that has no known meaning, this one appears
as the first component in gpr8 followed by s, t and r. Skip this
component when arrays are being used. Also implement CUBE texture types.

- Used by Pikmin 3: Deluxe Demo.
