There are a few more 2PC transactions in test_decoding (no
installcheck), temp.sql, test_extensions.sql and pg_stat_statements's
utility.sql (no installcheck) but their GIDs are not that bad.
twophase_stream.sql has a GID "test1", which is kind of generic, but
it won't run in parallel. At the end, only addressing the
prepared_xacts.sql and the ECPG bits looked enough to me, so I've
tweaked these with 7e61e4cc7cfc and called it a day.

I'd be curious about any discussion involving the structure of the
meson tests.
