Dynarec: Move CR0 into cpu_state

Some dynarec backends (x86-64, arm64) expect the offset between cpu_state and CR0 to within a certain limit, otherwise they crashes (e.g: "host_x86_MOV64_REG_ABS - out of range").
Move CR0 to the end of cpu_state, make sure the offset is within limit.

Helps NT4 and Win95 with dynarec on.
