wined3d: Add infrastructure for faking driver versions.

Often the Linux / MacOS graphics driver version is of no use for
finding a proper driver version to report to the D3D app. So this
patch adds some infrastructure for easy hardcoding of card specific
driver versions to report to the application. This helps applications
which make assumptions based on the driver version, like bug
workarounds.
