Add support for XP SP3 in the Virtual Print Driver.

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

Note that Chrome is supported on Windows XP SP 2, as well -

The virtual printer driver is a separate install.  For now, at least, it
will require SP3.  SP2 might be feasible, but it would require additional
research and complexity that doesn't make sense at the moment.

Patches are welcome. :-)
