Support mouse lock in Flash fullscreen mode.

In this mode, we won't show a bubble to ask for user permission. Mouse lock content settings are not considered, either.

BUG=129241
TEST=1) run ppapi/examples/mouse_lock;
     2) when one of the plugins is focused, press 'f' to enter Flash fullscreen;
     3) left click to enter mouse lock.
