use exceptions for better invalid index error reporting (bug #45957)
* lo-array-gripes.h, lo-array-gripes.cc (index_exception):
New base class for indexing errors.

(gripe_index_out_of_range): New overloaded function.
(gripe_invalid_index): New overloaded functions.
Delete version with no arguments.
(gripe_invalid_assignment_size, gripe_assignment_dimension_mismatch):
Delete.
Change uses of gripe functions as needed.

exceptions to collect error info about and handle indexing errors.

do_accumarray_minmax, do_accumarray_minmax_fun, F__accumdim_sum__):
Likewise.

tree_index_expression::lvalue): Likewise.
* Array-util.cc (sub2ind): Likewise.
* toplev.cc (main_loop): Also catch unhandled index_exception
exceptions.
* ov-base.cc (octave_base_value::index_vector): Improve error message.
* ov-re-sparse.cc (octave_sparse_matrix::index_vector): Likewise.
* ov-complex.cc (complex_index): New class.
(gripe_complex_index): New function.
(octave_complex::index_vector): Use it.
* pt-id.h, pt-id.cc (tree_identifier::is_variable,
tree_black_hole::is_variable): Now const.
* pt-idx.cc (final_index_error): New static function.
(tree_index_expression::rvalue, tree_index_expression::lvalue):
Use it.
