`MidCircuitMeasure` inherits `MidMeasureMP`

[mudit2812]

Context: MidCircuitMeasure inherits HybridOp but only relies on its tracing functionality and nothing else, but also contains a lot of attributes that make it more appropriate for it to be a child of MidMeasureMP instead of HybridOp.

Description of the Change:

• MidCircuitMeasure inherits MidMeasureMP and uses useful attributes for the new parent class.
• Update MidMeasureMP.trace_quantum to be compatible with the above change.
• Fixed an incorrect link in the changelog.

@mudit2812 Any chance we will see this improvement land or is it considered abandoned? 😅

@dime10 I wouldn't call it abandoned. Definitely think it's possible to get this in for 0.8, but it's just not a priority at the moment.
