Change "format_descriptor_format" implementation as suggested by @lal…
…aland. Additional tests meant to ensure consistency between py::format_descriptor<>, np.array, np.format_parser turn out to be useful only to highlight long-standing inconsistencies.

Remove the new
np.format_parser()-based test, it's much more distra……cting than useful.

Use
py::detail::compare_buffer_info<T>::compare()to validate the `……format_descriptor<T>::format()` strings.
-
Add
buffer_info::compare<T>to make `detail::compare_buffer_info<T>……::compare` more visible & accessible.
