nvs_flash: Add support for HMAC-based NVS encryption keys protection scheme 
- This features allows the NVS encryption keys to be derived and protected using
  the HMAC peripheral. Since the encryption keys are derived at runtime, they
  are not stored anywhere in the flash and hence this feature does not require
  a separate `nvs_keys` partition.

Mahavir Jain e67128dd0a nvs: add config to ignore "encrypted" flag of nvs partitions 
This is to allow having pre IDF v4.3 behavior where "encrypted"
flag was not being checked for NVS partitions.

It is recommended to enable this new config only if you have
production devices where NVS partition was being set with "encrypted"
flag by mistake.

Please see commit aca9ec28b3 which
introduced check to not allow NVS partitions with "encrypted" flag set.

Aditya Patwardhan a02be97fda nvs_flash: Modify the default NVS initialization API with internal nvs encryption 
handling (only when nvs encryption is enabled)
    * NVS Encryption will now be turned on by default with flash encryption
    * Updated the flash encryption example to shocase NVS encryption
    along with information on how to configure and use NVS encryption
    * Updated respective test case
    * Added two partition tables for NVS encryption
     i) Table 1- Single factory app, no OTA, encrypted NVS
     ii) Table 2- Factory app, Two OTA, encrypted NVS
