Subject: [PATCH] PageRowGlobalToolBarUI: don't animate opacity

Doing so causes flickering in System Settings and KInfoCenter because of
how the titles are rendered. It also doesn't make conceptual sense since
the style of toolbar generally doesn't change so the user would never
actually see the animated opacity change in the first place.

BUG: 417636
FIXED-IN: 5.89
