Close #1738 (this is a cherry-pick and fixup of that PR)

Related to #1770

Only works for exceptions that publicly derive from `std::exception`
and the matching is done exactly, including case and whitespace.

In the future, we will also want to introduce our own
`uniform_int_distribution` and `uniform_real_distribution` to get
repeatable test runs across different platforms.

It was used in checking that types in TEMPLATE_TEST_CASE and friends
were unique, but this was removed for v2.8.0 (#1628). Since there
are no further uses of this trait, the simplest thing to do is to
just remove it.

Fixes #1757
