[FREELDR] Abstract VGA BIOS specific code (#1736)
* [FREELDR] Abstract VGA BIOS specific code
WinLdrSetupSpecialDataPointers() uses INT 10h video interrupts, but they are not available on Xbox, so make them machine-specific.

* [FREELDR] Abstract getting extended BIOS data area
WinLdrSetupSpecialDataPointers() uses INT 15h AH=C1h to get extended BIOS data area, but it's not available on Xbox, so make it machine-specific.
