Get rid of MATERIAL_MAX_TEXTURES_USED

Browse Source 
Another configurable knob of questionable usefulness,
especially since this inhibits certain optimizations
by making loop length dependent on a global variable.

const u32 MATERIAL_MAX_TEXTURES = _IRR_MATERIAL_MAX_TEXTURES_;
//! By default this is identical to MATERIAL_MAX_TEXTURES
/** Users can modify this value if they are certain they don't need all
available textures per material in their application. For example if you
never need more than 2 textures per material you can set this to 2.
We (mostly) avoid dynamic memory in SMaterial, so the extra memory
will still be allocated. But by lowering MATERIAL_MAX_TEXTURES_USED the
material comparisons and assignments can be faster. Also several other
places in the engine can be faster when reducing this value to the limit
you need.
NOTE: This should only be changed once and before any call to createDevice.
NOTE: Do not set it below 1 or above the value of _IRR_MATERIAL_MAX_TEXTURES_.
NOTE: Going below 4 is usually not worth it.
