GPencil: Improve Cyclic operator to generate geometry

Now, when close a geometry with cyclic is possible generate new geometry for the gap.

The cyclic operator now supports multiframe edition too. Before only worked with active frame.

Also added the corresponding missing menu options and the new F keymap. All these features were missing, pending of the fix of the alpha glitches in stroke already done.
