[Transformation] Add a compiler pass that sinks measurement operations past independent ops

[cabreraam]

Adds a new sink-measurements that operates on funcOps and moves Quake measurement operations later within a block when doing so is semantically safe.
The pass sinks measurements past operations that do not consume the measurement result and do not touch the measured quantum target.
It uses conservative quantum alias checks, only proving non-aliasing for cases such as distinct local quake.alloca values or different constant-index quake.extract_ref values from the same local veq.

The barriers (ops we won't move measurement ops past) include:

• users of the measurement result, such as quake.discriminate
• operations that may alias the measured target
• other measurement operations
• region operations
• terminators
• side-effecting non-Quake operations

Adds cudaq/test/Transforms/sink_measurements.qke with coverage for

• cases where measurement ops can be sunk
• cases where we stop conservatively due to encountered barriers to sinking, i.e.,
  • aliasing
    • e.g., we cannot determine that two !quake.refs don't point to the same qubit
  • dynamic indices
    • e.g., runtime dependent indexing into veqs
  • whole veq operands
  • downstream ops depend on depend on measurement targets
  • region op
  • side-effecting classical ops.
