lib: shared resolvePatch, ensureStyle, logger; legacy wrapper code removed

- finders.js (VERSION 2): resolvePatch (resolveAll or the "signature not
  found, ... left unpatched" status), ensureStyle and logger, used by the
  patches instead of their own copies.
- hooks.js (VERSION 2) no longer unwinds per-patch wrappers of old patch
  versions; dashboard-windows and steam-close-button drop their handling of
  versions <= 2 / <= 6 (in-page only, gone with any SteamVR restart).
- VERSIONs: dashboard-windows 4, steam-close-button 9, window-curvature 21,
  frame-controls 7, steam-keyboard-patch 22, launcher-menu grid 7,
  pinned-desktop 4, show-all 2.
