Reviewed by Dean Jackson.

XRVisibilityState is tristate: Visible, VisibleBlurred, Hidden. Previously only
Visible was considered "visible" causing a JS SecurityError to be thrown when
reporting poses in the "blurred" state, ie. when WebXR doesn't have input but
should render.

This change considers both Visible states as "visible" and Hidden as "not
visible".
