ui: don't return certain layers when they are supposed to be displayed

This is a hack to distinguish visibility for a certain configuration. As we have
layers in place, we can give them a visibility, allowing us to have internal
settings switched on without them showing up in `hg showconfig`. This is useful
for extension to set a list of default flags to trigger behavior.
