[MCM-1] Add new gate library with MidCircuitMeasure instruction

[ElePT]

Summary

This PR contains a preliminary implementation of the MidCircuitMeasure instruction, an alternative measurement that can be added to a Target and used for circuit building and transpilation.

To use this gate, you can do:

from qiskit import QuantumCircuit
from qiskit_ibm_runtime.circuit import MidCircuitMeasure
from qiskit.circuit import Measure

circ = QuantumCircuit(2, 2)
circ.x(0)
circ.append(MidCircuitMeasure(), [0], [0])
circ.append(MidCircuitMeasure("measure_3"), [0], [1])
circ.measure([0], [0])
circ.measure_all()
print(circ.draw())

Details and comments

This is part of the implementation of #2287
