Fix test failures

This commit updates tests which started to fail because of the different
RNG behavior used by the parallel SabreSwap seed trials. For the most
part these are just mechanical changes that either changed the expected
layout with a fixed seed or updating a fixed seed so the output matches
the expected result. The one interesting case was the
TestTranspileLevelsSwap change which was caused by different swaps being
inserted that for optimization level enabled the 2q block optimization
passes to synthesize away the swap as part of its optimization. This was
fixed by changing the seed, but it was a different case than the other
failures.
