The motivation for this change is that this approach will no longer work
if we provide ISLE term signatures in the source code instead, as implemented
in #82. The term signatures will only be known later, at which point we can
use the TestResult::Expect callback to derive the expectation.
This PR replaces the
TestResult::MultiTypevariant with a callback that computes the expectedVerificationResultfor a providedTermSignature.The
MultiTypevariant was only used in a single test, where it was used to provide a list of expectations derived fromisle_inst_types().https://github.com/avanhatt/wasmtime/blob/575c137da4f90601f6542775ed40420d6524f5d0/cranelift/isle/veri/veri_engine/tests/veri.rs#L1102-L1126
