Added an API to verify the bootloader and app image before revoking the key in Secure Boot V2. This will help in preventing the device to be bricked if the bootloader/application cannot be verified by any other keys in efuse
Bootloader Support Component ============================ Overview -------- "Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app. Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
