Fix crash using 'Mesh > Normals > Point to Target' from the header menu

This was working from Alt+N menu but was passing wrong ARegion
(alongside wrong mouse coords) to ED_view3d_win_to_3d_int when called
from the header menu.

Operator context INVOKE_REGION_WIN takes care of this.

This also fixes wrong behavior of 'Mesh > Normals > Rotate' when called
from the header menu.
