[PMON] [Mellanox] fix syseepromd issue on simx (#8131)

Browse Source 
Avoid initializing sfp/thermal/components/fan/psu/leds on simx and create vpd_info file on hw_management when we use mellanox simulator platform

- Why I did it
this is a fix for issue in mellanox simulator platforms. the syseepromd failed on the pmon docker. also "decode-syseeprom" failed also

- How I did it
before initializing thermal/components/fan/psu/leds --> check if we are running on simx
creating the vpd_info on the hw_management folder.

- How to verify it
check if syseepromd process was loaded properly on the pmon docker.
decode-syseeprom is working well without errors/warnings
