This commit implements correct VI timings using VI registers rather than hardcoding the behavior for the default presets made by commercial games. This makes Ares behaves correctly, timing-wise, also with non standard timing like eg: the so-called PAL60 mode. Moreover, it fixes VI interrupts in interlaced mode to happen on the exact scanline they happen on the hardware, including known hardware bugs.
