DellEMC: S6100, Z9332f - Include ONIE version in 'show platform firmware status' (#10493)

Why I did it
To include ONIE version in show platform firmware status command output in DellEMC S6100 and Z9332f platforms.

How I did it
Include ‘ONIE’ in the list of components provided by platform APIs in DellEMC S6100 and Z9332f.
Unmount ONIE-BOOT if mounted using fast/soft/warm-reboot plugins in DellEMC S6100.
