Cleanup: UI: Shuffle icons and group them in categories

No functional changes.

The comments in the file are used as categories by some of our ICON
reading tools.

This also groups the TOGGLES icons together, with comments about their
order. This only includes the icons actively used as toggles at the
moment.

Note that ICON_NONE has always to be the first one in this file since
some parts of the code (e.g., the code to turn RECORD_ON into colored,
and the code for the popover chevron) have no-icon hardcoded as 0.
