NXP backend: Add post-quantization data utilization to aot_neutron_compile.py.

[MartinPavella]

Summary

A recent PR added the option to use the post-quantization state dict to access static data during quantization. This PR adds this feature to the aot_neutron_compile.py.

Test plan

Unit-test with the example MobileNetV2 is provided.

Pull request overview

Adds support in the NXP AOT compile example for using post-quantization model data (state dict) during partitioning/lowering, and introduces a regression test intended to validate end-to-end delegation for MobileNetV2.

Changes:

• Pass post_quantization_state_dict=module.state_dict() into NeutronPartitioner in aot_neutron_compile.py when delegation is enabled.
• Add a new pytest that runs the AOT example script for MobileNetV2 and inspects the produced .pte for delegation.

File	Description
examples/nxp/aot_neutron_compile.py	Provides post-quantization state dict to the partitioner so static tensors can be recovered during partitioning with fake tensors.
backends/nxp/tests/test_aot_example.py	Adds an end-to-end test that runs the example script and validates the serialized program contains Neutron delegation.

looks like it is failing to load from URL.

Maybe just use random weights + data instead of "real"?

The failing checks seem unrelated and the internal build passed. Merging.
