rpi-config: Add variables to set memory split for 256/512 models

GPU_MEM
gpu_mem - GPU memory in megabyte. Sets the memory split between the ARM and
GPU. ARM gets the remaining memory. Min 16. Default 64

GPU_MEM_256
gpu_mem_256 -GPU memory in megabyte for the 256MB Raspberry Pi. Ignored by
the 512MB RP. Overrides gpu_mem. Max 192.

GPU_MEM_512
gpu_mem_512 -GPU memory in megabyte for the 512MB Raspberry Pi. Ignored by
the 256MB RP. Overrides gpu_mem. Max 448.
