8f8341f qml: Introduce Tooltip for the BlockClock navbar button (johnny9)

Pull request description:

  The Tooltip will appear when hovering over the BlockClock tab button in the desktop navigation bar. It will show the current state of IBD.

  Two things are different than the figma. The wording for remaining blocks matches what is shown on the BlockClock instead of what the figma shows and After sync, Blockheight is shown instead. Looking for opinions on both during review.
