Add support for XP SP3 in the Virtual Print Driver.

Delayload winspool.drv and pull the files we need from fixed locations on XP instead of relying on core drivers.
On Vista and later the install flow is unchanged GetCorePrinterDrivers and GetPrinterDriverPackagePath are delayloaded so they don't crash on XP.
Needed to modify the CabinetCallback to handle the variable structure of the cabs on the different platforms.
Added an OS version check on startup.


BUG=112035
TEST=Install on XP SP3
