Overhaul close.m to add "force" argument (bug #44324)
* close.m: Emit an error if there is no figure handle or "all" argument given.
Check for "force" argument and delete the requested figure handles rather than
calling closereqfcn. Add BIST input validation tests. Add new calling forms
and explanation of "force" to docstring.
