[Mellanox] Change SDK API sx_mgmt_phy_module_info_get() to sysfs (#15963)

Browse Source 
- Why I did it
Change Mellanox platform API implementation to use ASIC driver sysfs for the module operational state and status error fields.

- How I did it
Modify the platform/mellanox/mlnx-platform-api/sonic_platform/sfp.py file by change the call of sx_mgmt_phy_module_info_get() SDK API to sysfs

- How to verify it
Simulate the unplug cable event
Check the CLI output
sfputil show presence
sfputil show error-status -hw
Simulate the plug cable event
Repeat 2 step
