Shift slot number to slot behavior mapping by six slots in H40 mode. This makes the line change slot align with the point at which the display turns on and off at the end of the active display area. Also fixed a regression in which an external slot got accidentally changed into a sprite draw slot

Update vscroll latch implementation to be more in line with what Eke-Eke has observed. Revert the change to vdp_cycles_to_line because it breaks hints on line 0. H-Int timing is still a little messed up, but the previous change made things worse.

Partially working switch to having a vcounter and hslot counter in the context rather than trying to derive them from the cycle count. This should allow for more accurate handling of mid screen mode switches. Interrupt timing is broken currently though

Fix DMA fill so that it does not cause observable changes to the FIFO. Get DMA copy mostly correct from an observable ffect perspective. DMA copy probably does not reflect internal implementation still given that evidence seems to suggest no FIFO usage at all.
