Connect to OQD device runtime from Python layer

[mehrdad2m]

Context:
A boilerplate Python OQD device was added in PR #1355. We want to verify that the infrastructure introduced in that PR is sufficient to generate OpenAPL in the runtime.

Description of the Change:
Added get_c_interface method for the OQD device to be able to point to the c++ implementation of the device in python.
This makes qjit to accept an instance of the OQD device and be able to connect to its runtime.

Benefits:
This allows for OQD runtime to be exposed to python, unlocking the next steps which are implementing the llvm lowering and the runtime methods.

Possible Drawbacks:
