Subject: [PATCH] tst_qxp_function_ref: check that function_ref's are trivially
 copyable

Mandated by P0792R9 already, but we never checked and P0792R14 has
user-defaulted assignment operators showing up in the synopsis now,
so make sure we don't accidentally break this going forward.

Amends 29b65c98e720056e87334ce88a683969e57efd3d.

Pick-to: 6.5
