DMA: Run manual channels while halted
...
Fixes games which have looping linked lists but still expect CD/OTC
reads to work.
Also caps the number of ticks used when looping linked lists are
present, which doesn't steal so much time from the CPU per batch.
Fixes:
- Victory Spike
- Magical Drop III - Yokubari Tokudai-gou!
- Yuukyuu no Eden - The Eternal Eden
- Loading screen in World Cup Golf - Professional Edition

GPU: Implement FIFO and timings
...
This will cause a slight performance loss. I've left some knobs in which
can be tweaked to mitigate this, but the goal is to be compatible with
all games which require them.

DMA: Remove timing events
...
We'll probably need to revert/re-add a variant of this when we
eventually implement chopping. But for now it simplifies things.

Revert "DMA: Delay GPU transfers by block count"
...
This reverts commit 0639f4264f0b9b40d99e0e5ce40f4eda91bc881d.
Breaks FF7's FMVs in the top row. Needs GPU timings.
