/** @brief Verify the secure boot signature block for Secure Boot V2.
*
* Performs RSA-PSS or ECDSA verification of the SHA-256 image based on the public key
* in the signature block, compared against the public key digest stored in efuse.
*
* Similar to esp_secure_boot_verify_signature(), but can be used when the digest is precalculated.
* @param[in] sig_block Pointer to signature block data
* @param[in] image_digest Pointer to 32 byte buffer holding SHA-256 hash.
* @param[out] verified_digest Pointer to 32 byte buffer that will receive verified digest if verification completes. (Used during bootloader implementation only, result is invalid otherwise.)
