In response to #50998 (as well as #87892 indirectly),
regarding adding sinusoidal and coil-like shapes to the
shape gallery in LibreOffice, this commit adds a sinusoid
shape to the gallery.
The shape is still incomplete for release, at least lacking
icons for the sidebar. Further details posted on the Bugzilla
thread for issue #50998.
PS-2: Removed the previously added flag shape.
PS-4: Moved sinusoid to the end in a new subgroup.
