Boot: Add RSA-3072 support to MCUBoot

PSA TBSA-M recommends to use RSA signature for firmware
authentication with at least 3072 bits length key size.
This patch introduces:
- add an example RSA-3072 key
- add configurable RSA-3072 support (RSA-2048 still available)
- set RSA-3072 to default

This change is based on:
