Commit Message

Use nalgebra matrices for uncommon paths in consolidate blocks (#15881)

In the recently merged #15871 we updated the consolidate blocks pass to
use Matrix4 in the common path of a 2q block being consolidated. This is
like > 90% of what the pass does when run in the preset pass manager.
However, there were uncommon cases in the pass around the handling of
blocks of a single gate that are outside of the target which were not
updated to use nalgebra arrays if it's a fixed size 1q or 2q gate. This
commit updates these uncommon paths so that we're always returning an
nalgebra matrix in the output UnitaryGate if the block being consolidated
is a single qubit or two qubits.
