libdm: report: add dm_report_destroy_rows

Calling dm_report_destroy_rows makes it possible to destroy any report
content we have but at the same time it doesn't destroy the report
handle itself, thus it's possible to reuse that handle again for new
report content.

Functionally, this is the same as calling dm_report_output with the
report handle but omitting the output iself. This functionality may
be useful if we, for whatever reason, need to discard the report
content and start a fresh new one but with the same report configuration
and initialization and thus we can just reuse the existing handle.
