winemac: Restore app cursor settings when cursor moves back into an app window.

The code had previously set the cursor back to the standard arrow and unhid
it when it left all app windows.  Now it restores the cursor image that the
app set and re-hides it if necessary when it moves back over any app window.

(cherry picked from commit 1c049e5031ff6ca3dc2ee874493aa6e685e8e9c2)
