UI: Header / Tool Settings: Show tool icon when tools are collapsed

Show the scaled down tool icon when the tool region is collapsed. Show a
blank space when the tool region is visible.

* Minimize the UI flickering when changing the active tool.
* Show the active tool when the tool region is collapsed.
* Smaler header footprint (the tool name is not visible).

This is a follow up for T91536.
