GPencil UI: Expand Sculpt Settings panel by default

Sculpt settings are often quite handy to be able to easily access while drawing,
so make it easier to access these when drawing without having to first expand
the panel.

(On the other hand, the "Edit Strokes" panel contains tools already found in
various other places - menus,etc. - so no need to expand it by default)
