vgacon: remove prehistoric macros
These macros: * CAN_LOAD_EGA_FONTS * CAN_LOAD_PALETTE * TRIDENT_GLITCH * VGA_CAN_DO_64KB * SLOW_VGA are either always set or always unset. They come from the linux 2.1 times. And given nobody switched them to some configurable options, I assume nobody actually uses them. So remove the macros and leave in place appropriate branches of the conditional code.
