Support FIPS DB configuration (#15632)

Why I did it
Support FIPS DB configuration
Design Doc: sonic-net/SONiC#1372

Work item tracking
Microsoft ADO (number only): 24411148
How I did it
Add the FIPS Yang model to make FIPS configurable in ConfigDB.

How to verify it
See TestPlan: sonic-net/sonic-mgmt#9092
Build the image and run the tests: sonic-net/sonic-mgmt#9091
