Check DirectCompositionOverlays field trial only if hardware supports it
On most systems the hardware doesn't actually support it, which means
that gathered statistics for the enabled group also include a lot of
machines that don't use overlays, which makes analysis difficult.
This change causes the overlay detection code to always run (on Win10
with DirectComposition enabled), but it seems fast and stable enough
for that not to be an issue.
