Modify the logic that cable can be reset or not (sonic-net#6085)

For some plaform, the SFP cable can not reset, and for some platform the cable maybe RJ45
Add the option --unresettable_xcvr_types to let customer specify the type which type can not reset

- What is the motivation for this PR?
Modify the logic for check if the cable can be reset or not

- How did you do it?
Add option --unresettable_xcvr_types to let customer specify which types are not support to reset

- How did you verify/test it?
Run the test_sfp.py::test_reset on with the SFP port, the test can pass
py.test platform_tests/api/test_sfp.py::TestSfpApi::test_reset --unresettable_xcvr_types "SFP"
py.test platform_tests/api/test_sfp.py::TestSfpApi::test_reset --unresettable_xcvr_types "SFP" --unresettable_xcvr_types "RJ45"

- Any platform specific information?
No

- Supported testbed topology if it's a new test case?
No
