Remove Optimize1qGatesDecomposition from init stage (#11360)

In #11354 we added more logical optimization passes to the preset pass
managers for level 1, 2, and 3 which included the
Optimize1qGatesDecomposition pass. However, this had the the unintended
side effect of tending to normalize circuits to use parameterized gates.
This becomes an issue for discrete basis targets as the basis translator
doesn't always know how to work with those. To avoid issues this commit
removes the pass from the init stage and just saves it for the
optimization loop. If we want to do 1q gate simplification during init
in the future we can develop a different pass that does it in a manner
that wouldn't interfere with discrete basis targets like
Optimize1qGatesDecomposition.
