Remove constraint on zooming in using mouse wheel in TimelineOverview

With a hard-wired limit on the minimal timline overview window width we often cannot zoom in enough in the CPU flame chart to see the full text in a single sample bar. This change removes that limit while still preserving minimal window width in th UI.
