    docs/xentop: Add documentation for physical CPU monitoring feature
    
    Add man page documentation for the new '-p/--pcpus' flag that displays
    physical CPU utilization metrics. This provides hypervisor-level CPU
    usage insights alongside existing domain statistics.
    
    Changes include:
    - Add '-p' flag to SYNOPSIS section
    - Document '--pcpus' option with description
    - Maintain consistency with existing documentation style
