device/pci_rom: Add vga_oprom_preload

This method will allow preloading the VGA_BIOS_FILE. By preloading the
file, into cbfs_cache we reduce boot time. In the future we can also add
support for loading the second VGA_BIOS_FILE and the DGPU VGA_BIOS_FILE.

BUG=b:179699789
TEST=Boot guybrush to OS and verify 12 ms reduction in boot time
