Fix T94243: weightpaint gradient panel shown in other places

Weightpaint gradient tool panel showed in other modes (and as a separate
panel).

Fix for fix, see
- rBf8a0e102cf5e
- rBe549d6c1bd2d

So now, check mode again and restrict to topbar (prevents an additional
panel since this is already included in the brush settings).

ref rB0837926740b3 in sculpt-dev branch, so thx @joeedh as well!
