higan Changelog：
- md/vdp: added full interlace emulation [byuu, Sik, Eke, Mask of
Destiny]
- md/vdp: fix an issue with overscan/highlight when setting was
disabled [hex\_usr]
- md/vdp: serialize field, and all oam/objects state
- icarus/md: do not enable RAM unless header 0x1b0-1b1 == "RA"
[hex\_usr]

I really can't believe how difficult the interlace support was to add. I
must have tried a hundred combinations of adjusting Y, Vscroll, tile
addressing, heights, etc. Many of the changes were a wash that improved
some things, regressed others.

In the end I ended up needing input from three different people to
implement what should have been trivial. I don't know if the Mega Drive
is just that weird, if I've declined that much in skill since the days
when I implemented SNES interlace, or if I've just never been that good.

But either way, I'm disappointed in myself for not being able to figure
either this or shadow/highlight out on my own. Yet I'm extremely
grateful to my friends for helping carry me when I get stuck.

Since it wasn't ever documented before, I'm going to try and document
the changes necessary to implement interlace mode for any future
emudevs.
