vmwgfx: Add an option for direct presents
With this option set to true, accelerated copies to a scanout pixmap will
be performed as hardware presents instead of copies to an intermediate
3D surface backing the scanout pixmap, followed by a present.
Depending on the application this might be a performance boost, but since
it might trigger device software readbacks in other situations, for example
dri2 copy front->fake_front, it might be a performance hog in other situations,
so disable it by default. (Before this commit it was enabled by default).
