Add new '--boot-record' option for imgtool to add a new type of TLV to
the image manifest called BOOT_RECORD. This TLV contains CBOR encoded
data with some basic information about the image (SW component) it
belongs to, these are the following:
- SW type (role of the software component)
- SW version
- Signer ID (identifies the signing authority)
- Measurement value (hash of the image)
- Measurement type (algorithm used to calculate the measurement value)
The boot_record.py file and most of the modifications in image.py are
coming from the Trusted Firmware-M project
(https://www.trustedfirmware.org/about/).
Hash of the source commit: 08d5572b4bcee306d8cf709c2200359a22d5b72c.
This patch is based on the recommendations of Arm's Platform Security
Architecture (PSA) and its purpose is to support compliance with it.

support for signing images in this format in imgtool.

Instead of relying on distro packages standardize the imgtool
dependencies into a requirements.txt.
