libobs: Change service max res. to res. list

(This commit also modifies rtmp-services and UI)

Changes the maximum resolution size to a resolution list, and splits the
maximum FPS to its own function.

(Note: ABI has not been modified because the last changes still haven't
been released yet, so it's safe to modify this as long as the changes
haven't been officially released)
