✨ MLIR - Hybrid Circuit Optimization with Qubit Reuse

[DRovara]

Description

This PR provides two main functionalities, each accessible through its own transformation pass:

• lift-measurements: Attempts to move measurements over other gates, if that is possible (e.g. over controls or phase gates).
• qubit-reuse: Attempts to reduce the number of required qubits by reusing existing qubits that are no longer necessary, when possible.
