render: Plug a memory leak in AddGlyph. (#23286)
AddGlyph was missing the FreePicture() call that DeleteGlyph used, resulting
in a memory leak when more than one Glyph was added in a RenderAddGlyphs
request.
Since the code in AddGlyph and DeleteGlyph is identical, move into a static
function to avoid such mistakes in the future.
