Subject: [PATCH 1/2] Outline intensity setting

This MR adds a tiny outline intensity combobox to Breeze settings in the Shadow tab.
I chose shadow tab since the outline is drawn in the shadow drawcall,
so maybe this will help people realise it's not part of the borders.

BUG: 465948
FIXED-IN: 6.0

Here's examples with default breeze dark theme

Maximum

Currently the effect only appears after pressing OK. This is same with all the Breeze window decoration settings afaik.

_Also, dont mind the settings window having same outline at the same time in the images: I'm not using the dev environment so it doesnt affect anything outside of the preview image. In dev env it changes everywhere._
