Reapply "OvmfPkg/QemuVideoDxe: VMWare SVGA device support"

Browse Source 
This reverts commit 98856a724c, reapplying
c137d95081.

Note that the commit now being reverted is technically correct; the only
reason we're reverting it is because it should not have been pushed past
the Soft Feature Freeze for the edk2-stable201811 tag.
