But only enable it when using a PS2 BIOS. I could put the check in the
handler registration, but realistically this is basically never going to
be called, so better to keep things simple.

baked into save states.

Bus: Implement RAM_SIZE register
...
Fixes Rock-Climbing - Mitouhou e no Chousen - Alps Hen (Japan) crashing
on boot. Silly game does a 512 word DMA from CDROM to 0x001FFF04, with the
mapped memory size set to 4MB, expecting the DMA to trigger a bus error,
because if it doesn't, then your kernel memory goes bye bye.
A bunch of other games do set the upper 4MB to be unmapped, but this
change appears to have no effect on them. As expected, they're probably
doing the correct thing.

CPU/CodeCache: Dynamically compute BIOS memory access timing
...
The timings can change if the game does so. Instead of forcing the
blocks to recompile, we can just manually multiply size * word_time.
Improves stability of Nightmare Creatures booting, and fixes corrupted
text in Formula Circus when using the cached interpreter.
