xfree86/modes: Disambiguate driverIsPerformingTransform

The driver can now specify exactly which aspects of the transform it
wants to handle via XF86DriverTransform* flags.

Since the driver can now choose whether it wants to receive transformed
or untransformed cursor coordinates, xf86CrtcTransformCursorPos no
longer needs to be available to drivers, so make it static.
