Add Python API for specifying device options. (#4205)
* Add python API for specifying CUDA device id

* Modification for providing session based python api for specifying
device id

* When include header file pybind11/stl.h, conversion between c++
containers and Python list, vector and dict data structure are
automatically enabled.

https://pybind11.readthedocs.io/en/stable/advanced/cast/stl.html#

Therefore, refactor the code for better leverage this advantage.

* Make struct CudaDeviceOptions as default cuda device options

* Implement sess.set_providers(list_of_providers, list_of_provider_option_dicts)

But still stay consistent with existing sess.set_providers(list_of_provider)

* Add cuda provider option default setting

* Add support for setting cuda cuda_mem_limit and arena_extend_strategy.
Also resolved the merge conflict on session.py

* Use python ctypes to call cuda library to help python unittest

* Refine the code with reviewer's suggestions

* Add the capability of getting execution provider's configuration

- Once we introduced the capability to set execution provider's
configuration, it makes sense to add capability of getting ep's configuration.

* Modify the code with reviewer's suggestions.

* Using stoull() and stoul() depends on 32/64-bits architecture.

* Rewrite the testcases for testing setting CUDA device id

Note: We need to make sure every ORT process be run on one CUDA device
at a time.

* Make sure old session object is destroyed by python gc before new
session object is being created

* Move testcases to original onnxruntime_test_python.py

* Fix bugs to pass CI build

* Make it pass CI build (cont.)

* Make it pass CI build (cont.)
