"resize" result can be wrong if method="nearest_neighbor" and
coordinate_transformation_mode="asymmetric" and rounding_method != "floor" and
target_height, target_width = n * image_height, m * image_width (n,m are
integers).
#12567
in buggy implementation:
`can_convert_multiply_to_intdiv` returns `True` if `scaled_size` is n times
`origin_size`, which will result in that `get_closest_index` converts the
mapped coordinate by `astype('int32')` without checking `rounding_method`.
in this implementation:
`can_convert_multiply_to_intdiv` returns `True` if `origin_size` is n times
`scaled_size`, which means that any coordinate in target_image will be mapped
into an integer coordinate in the origin_image. Therefore `get_closest_index`
do the `astype(`int32`)` in correct scenario.
