Added show platform firmware status command

[Deepak-Pandey]

MS ADO: 37718014

Why I did it

Added gNMI getter for show platform firmware status so client can fetch platform information via gNMI in JSON format.

How I did it

Added getPlatformFirmware() function which uses nsenter to get data from Platform() api.

How to verify it

admin@<machine>:~$ show platform firmware status

Looks like chassis and module might be invariant across all rows.
Can you verify the o/p of fwutil command which python is using.
If chassis and model is coming only once they we should have json:

{
  "chassis": "SN5640",
  "module": "N/A",
  "components": [
    {
      "name": "ONIE",
      "version": "2024.08-5.3.0013-9600",
      "description": "ONIE - Open Network Install Environment"
    },
...
..
}
