[ConstantFold][SVE][NFC] Add test for select instruction in scalable vector.

Browse Source 
Side notes from D73669, no need to guard the iteration on vectors, as
it is explicitly looking for a ConstantVector/ConstantDataVector, which
is not expected to be scalable at the moment. So, add the test only.
