entity_instance: get_info_2 falls back to get_info for unsupported args #4270

get_info_2 advertises the same signature as get_info but raised a bare
AssertionError for anything the C++ fast path does not implement --
including its own default arguments (recursive=False).

Use the fast path when recursive=True, return_type=dict and ignore=()
hold, and delegate to the pure Python get_info otherwise. As noted in
the issue, without recursion there is no meaningful performance gain to
lose by delegating.
