Add regression test for short varlenas saved in TOAST relations toast_save_datum() has for a very long time some code able to handle short varlenas (values up to 126 bytes reduced to a 1-byte header), converting such varlenas to an external on-disk TOAST pointer with the value saved uncompressed in the secondary TOAST relation.
There was zero coverage for this code path. This commit adds a test able to exercise it, relying on two external attributes, one with a low toast_tuple_target, so as it is possible to trigger the threshold for the insertion of short varlenas into the TOAST relation.
