Handle memory access size restrictions depending on transfer source #257

For instance VDP2 registers can't be directly written as bytes, but DMA transfer can. Needs further investigations to know where to apply this reasoning and how to implement it.

Needs to use direct memory copy when transferring through the DMA, instead of using the regular memory handlers. This way writes won't be traced.
