Chef::Node::ImmutableArray#short_circuit_attr_levels

This can be set to e.g. [ :@default ] by the parent container to cause this container
to only use the default level and to bypass deep merging (the common case is either
default-level or automatic-level and we aren't doing any deep merging).  Right now it
"optimized" for the case where we're no longer merging anything and only tracking a
single level, and setting this to anything other than a size=1 array would behave
in a broken fashion.  That could be fixed, but the perf boost would likely not be
that large in the typical case.
