Settings: show DLSS override version in dropdown/description, and

remove unused mark from DLSS-RR preset E.

Tries to parse nvngx_config.txt and find the latest override version,
displays it in dropdown.

Needs testing with systems that have modified nvngx_config (eg. through
updating DLSS override with tools), may release test version for it
soon.
