Boot: integrate MCUBoot with TF-M to act as a BL2 bootloader
Modifications in MCUBoot to be aligned with BL2 requirements in TF-M:
-- OS dependency was removed, no need to copy any OS repo to build it
-- CMSIS serial driver is used
-- flash driver interface is aligned with original version
-- S and NS images are handeled as a single binary blob
-- automatic image concatenation and signing at build time
-- authentication based on SHA256 and RSA-2048 digital signature
-- mbedTLS library is used for cryptographic operation
-- static analyser warnings fixed in some files
