HV:Modularize vpic code to remove usage of acrn_vm

Browse Source 
V1:Initial Patch
Modularize vpic. The current patch reduces the usage
of acrn_vm inside the vpic.c file.
Due to the global natire of register_pio_handler, where
acrn_vm is being passed, some usage remains.
These needs to be a separate "interface" file.
That will come in smaller newer patch provided
this patch is accepted.

V2:
Incorporated comments from Jason.

V3:
Fixed some MISRA-C Violations.
