find symbols in proper scope when debugging (bug #40397)

Delete member variable and all uses.
(lexical_feedback::symbol_table_context::pop): Assert that the context
is not empty before popping.
(lexical_feedback::symbol_table_context::push): Use default argument.
(lexical_feedback::symbol_table_context::curr_scope): If empty, return
symbol_table::current_scope, not the initial scope in effect when the
object is created.
* oct-parse.in.yy (octave_base_parser::make_anon_fcn_handle,
octave_base_parser::recover_from_parsing_function):
Don't check for empty lexer.symtab_context here.
