fix(esp_hw_support): Update key manager support 
1) Added new Key Manager APIs
    2) Added crypto locking layer for Key Manager
    3) Remove support for deploying known key
    4) Format key manager support
    5) Fix build header error
    6) Updated the key_mgr_types.h file
    7) Added key manager tests
