Update GFXTextureManager and GBitmap

Browse source 
GBitmap Changes:
Added all other formats to gbitmap that we support
gbitmap now supports cubemaps
added converters for all these other formats
added stb_image_resize for extrudemips so we can extrude mipmaps for all other formats

GFXTextureManager
Can now directly make cubemaps and texture arrays based on the GFXTextureProfile
API implementations for all functions that cubemaps and arrays needed
