Expose recovery img state as StandbySpare

In order to differentiate the recovery & active image,
StandbySpare or Active value will be advertised accordingly
by the inventory objects.

Tested:
1. Verified that BMC / BIOS active or recovery image
advertise the changes as Active / StandbySpare for the
Activation state
2. With changes in bmcweb, the same will be marked
as enabled / StandbySpare in the redfish schema query
for the State property
