Make Path tool deselect all points on single-click, and select all on…

… double-click, of shape's fill (#2148)

* Implement deselect on single-click and select all anchors on double-click

* fixed the single_click_behaviour

* fix flipSmoothSharp when doubleclick and drag

* Cleanup and Clippy fixes
