inspect({focus: false}): skip panel switch when omitFocus is set

When inspect(element, {focus: false}) is called, the V8 backend sends
an omitFocus hint via Runtime.inspectRequested. Previously the frontend
still switched to the Elements panel but merely avoided focusing the
node within it. Per reviewer feedback, the intent of {focus: false} is
to select the node in the Elements panel without switching the active
panel at all.

Change DOMNodeRevealer to pass {showPanel: false} when omitFocus is
true, so the panel selection is updated silently for the next time
the user opens the Elements panel.
