Remove advanced room logging setting

Fixes https://github.com/vector-im/element-web/issues/14602

This has proven to be less useful month over month, so it's time for it to go. The initial goal for keeping it was to track stability in the ~6 months post-release, which means it should have left around the start of 2021. At the time, Spaces was on the horizon with room list corruption issues though, so it was put on hold. These days, it's rock solid and doesn't appear to be causing issues. As such, the logging can leave in favour of more specific/targeted logging when we need it.

This might even speed things up as it's not hitting the SettingsStore every 0.2 seconds.
