accel: Rename HAX 'struct hax_vcpu_state' -> AccelCPUState

Browse source 
We want all accelerators to share the same opaque pointer in
CPUState. Start with the HAX context, renaming its forward
declarated structure 'hax_vcpu_state' as 'AccelCPUState'.
Document the CPUState field. Directly use the typedef.

Remove the amusing but now unnecessary casts in NVMM / WHPX.
