UI: Open 'Passes' panel by default in Cycles

This panel is arguably the most important in the ViewLayer properties, so
the concept of "1 panel open per context" doesn't work. Especially since
the first panel (View Layer) contains only two settings.

This also registers the Passes panels before filter/override so it's sorted in the same way as EEVEE.
