OvmfPkg: Add QemuVideoDxe driver
This driver provides a UEFI Graphics Output Protocol (GOP) driver
for the QEMU Cirrus VGA hardware. It enables 24-bit color,
and uses the standard 32-bit GOP pixel format whenever possible.
git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11524 6f19259b-4bc3-4df7-8a09-765794883524
