Remove kOzoneTestSingleOverlaySupport.

Remove kOzoneTestSingleOverlaySupport.

kOzoneTestSingleOverlaySupport was originally added to test a single
overlay plane when using Ozone.

The code evolved and now passing that parameter enable overlays (not
only a single overlay).

This CL removes the command line flag and uses kEnableHardwareOverlays
instead to enable overlays on Ozone.
