fix(editor): tweak freedraw settings and tablet UI/UX (#11551)

* fix(editor): align constant freedraw stroke width more with generic shapes

* reduce streamline for non-mouse

* do not change `currentItemStrokeVariability` unintentionally

* render penMode button under compact styles panel on tablets

* show stroke variability as standalone button in compact actions menu

* improve toolbar clicking UX with pen

* change streamline defaults

* change to `variable` stroke if toggling penMode for the first time
