Add CHECK_FOR_INTERRUPTS() in scram_SaltedPassword() for the backend
scram_SaltedPassword() could take a long time to compute when the number
of iterations used is large enough, and this code uses a tight loop to
compute a salted password.
Note that the same issue exists in libpq when using \password and a
large iteration number, but this cannot be interrupted. A CFI in the
backend is useful for server-side computations, at least.
Backpatch down to 16, where the user-settable GUC scram_iterations has
been added.
