[rocprofiler-compute] Add database output format to analyze mode (#748)

Analysis data dump

* Add `--output-format` and `--output-name` option to analyze mode

* Remove `--output` and `-save-dfs` option to analyze mode

* Add documentation on `rocpd` output format and analysis database file

* Create sqlite3 database using object relation mapping (ORM) provided
  by sqlalchemy library

* Fix metrics config to remove metrics marked as `null`, fix `Unit` header, add
  missing `title`

* Add test cases to ensure analysis data dump work
