Check both flags with an || since user can take both paths with python, cpp api, and ENV variables

I kept the !int8_calibration_table_name_ variable, since it takes both cases in count. I've tested with setting environment variable and using provider_options ; both works with priority of ENV. I do not see the approach for simplifying more than this. What's your opinion and suggestion? @TedThemistokleous I think if this works; we should add this PR and put in backlog ticket if there is better way to do approach this.

This change is needed when using MIGraphX environment variables inside scripts.
Previously, if we set:
os.environ["ORT_MIGRAPHX_INT8_CALIBRATION_TABLE_NAME"] = "calibration.flatbuffers"the int8_calibration_cache_available_ flag was not set correctly. We only encoded values from provider_options because we used info.int8_calibration_table_name, so the env var was ignored.
