config-tools: genertate performance policy parameter

Browse Source 
This patch is to generate an ACRN CPU performance policy type boot
parameter.

The generated parameter is either 'cpu_perf_policy=Performance’ or
‘cpu_perf_policy=Nominal’, according to the 'CPU performance policy type'
config item in configurator.

It will then be packed into acrn-hypervisor deb file, and will be
automatically added to grub cfg file through installation.
