    handbook/virtualization: add note on workaround for Parallels
    
    A user reported high CPU utilization on a fresh install of 14.0
    on Parallels (MacOS, M1/Apple Silicon).  Disabling the new ACPI
    ged(4) device worked around the problem.  Document this (for now).

 Without this setting, an idle FreeBSD Parallels guest will use roughly 15% of the CPU of a single processor iMac(R).
 After this change the usage will be closer to 5%.
