Always show the triage view when opening a shared cache or kernel cache

BinaryViewType gains a HasNoInitialContent function that views can use
to suppress layout restoration when opening a file. The layout will
still be restored when the view is loaded from a saved database.

Fixes https://github.com/Vector35/binaryninja-api/issues/8083.
