UI: Log streaming service recommended maximums

[prgmitchell]

Description

Log the maximum recommended audio and video bitrate when the user ticks the "Ignore streaming service setting recommendations" box.

Motivation and Context

Mentioned by @Warchamp7 that we should warn when a user is going above the recommended bitrate in the loganalyzer, this logging is a requirement to make that happen.

How Has This Been Tested?

Tested Twitch and Youtube in both simple and advanced output mode, both showed the correct values. Tested with "Custom" to confirm it is showing "None" for audio and video bitrate maximums when those values are returning 0. https://obsproject.com/logs/ZuadI85OgoP0Yjjj
