Add SHA-512 capability to MCUBoot

Description

Digest size is 512 bit, hash function computed with 64-bit words.
tweetnacl supports only this hash function.

A new type is needed to support it.
Should be a config variable for the user to choose if desired.

Also needs support to 'newt' 'imgtool' and 'imgtool.py' for this new hash.
