This commit adds the basis translation step to the level 2 preset
passmanager's optimization loop. The level 2 optimization loop runs the
commutative cancellation pass which use Rx and U1 gates as part of it's
optimization step which may not be in the target basis gates. This can
result in a gate outside of the target basis ended up in the output. To
avoid this in a general manner we need to rely on the basis translation
step because we can't write a pass to do the simplified rotation in a
manner compatible with any basis (especially since the target basis
could be using custom gates).

Fixes Qiskit#5644
