What

This PR introduces the filter widget to the time panel. In doing so, it deals with several shenanigans:

• The item collapsedness must not be shared between the unfiltered view, and across different filtering sessions
  Note: the collapsed state being persisted, we are now accumulating collapsedness state for every single filter session in the persistant storage. This is not ideal, but addressing that would required rolling our own collapsed state, which would leak all over the place (list item and many of its users).
• The collapse/expend all context menu must be made aware of what precedes.
• The time panel filter state must be invalidated upon switching active recording (otherwise it's weird UX).
• The streams tree UI area needs to have a minimum width otherwise search icon placement/layout breaks.

And of course the actual filtering logic must be implement. For now, the semantics are: "one of the entity part must contain the query string in its entirety". This is very (too) basic and will evolve in future PR (see #8586 (comment)).

Next step

Major next steps:

• have filters in more places (primarily blueprint tree)
• make the filter semantics more useful
