Improve log settings experience

Switch from the OverflowMenu to a custom Popover to improve the user
experience of toggling log levels. The OverflowMenu approach closes
the menu on each change requiring multiple additional clicks for each
log level the user wishes to toggle. With the Popover we can now keep
the menu open until explicitly dismissed, meaning users can much more
easily make multiple changes.

Also display a notice at the start of the logs if lines are hidden
due to the currently selected log levels.
