Don't list non-public or hidden functions from methods() (bug #64066)
* ov-classdef.cc (Fproperties): Use property name from property_map variable
, which is already known, rather than calling get_name() method which causes
cascade of multiple methods to be invoked.
* ov-classdef.cc (F__methods__): Change function signature to return a flag
"found" if input was a classdef class or instance. Add code to check "Access"
and "Hidden" properties before including in list of methods. Add BIST test
for __methods__.
* methods.m: Use second output from __methods__ to determine whether
__methods__ call was successful.
