utils: Never return a group_id of 0, add GST_GROUP_ID_INVALID

Various plugins use special values (0 or G_MAXUINT32) as an
invalid/unset group_id, but nothing guarantees a groupid won't have
that value.

Instead define a value which group_id will never have and make
gst_group_id_next() always return a value different from that.

API: GST_GROUP_ID_INVALID
