acrn-config: Generate info in pci_dev file for Pre-Launched VMs

Browse Source 
Pre-Launched VMs need the vbar_base values pre-populated
for pass-thru PCI devices.

This patch moves the pci parser logic from board_cfg_gen to library
so that scenario_cfg_gen scripts can use pci parser routines while
generating pci_dev file logical partition scenario.
