[sample] Detect measurement operations, disallow on hardware targets, warning on simulators

[khalatepradnya]

This PR introduces explicit detection and propagation of measurement operations within quantum kernels and enforces new restrictions and warnings when using the sample API with kernels that contain explicit measurements.

• Added a hasMeasurements flag to the QuakeMetadata struct and logic to detect measurement operations in MLIR passes, setting the hasMeasurements attribute on functions when found.
• Updated the metadata propagation pass to propagate both qubitMeasurementFeedback and hasMeasurements attributes through the call graph.
• Introduced a hasMeasurements attribute to Python kernel builders, setting it whenever an explicit measurement (mz, mx, or my) is performed.
• Updated the runtime and sampling logic in both Python and C++ to check for the presence of explicit measurements in kernels, raising errors on hardware targets and warning on simulators.

• Figure out proper handling for explicit_measurements option.
