Show occluded layers in SF view by default

The rects view should include visible + occluded layers by default and
only visible layers when the checkbox `only visible` is checked.

Currently it shows only visible layers in both cases

Bug: 262550235
Test: open a SF trace in winscope and check if occluded layer rects
appear
