Leverage Rust circuit sequence construction for OneQubitEulerDecomposer

This commit is a follow-up to Qiskit#9578 which added a rust implementation
of the second half of the single qubit euler decomposition routines and
leveraged them for the Optimize1qGatesDecomposition transpiler pass.
With that PR the Optimize1qGatesDecomposition no longer was dependent on
the OneQubitEulerDecomposer class. This commit continues from that PR
and updates the OneQubitEulerDecomposer to leverage the same Rust
implementation internally. Calling a decomposer object will internally
call the rust function to generate a circuit sequence and then return
either a QuantumCircuit or DAGCircuit (depending on the options).
Similarly all the angle computation is done directly in Rust.
