This patch adds RSA4096 key management to the SBSFU project.
It is related to the ST forum posts:
https://community.st.com/t5/stm32-mcus-security/secure-boot-rsa4096-stm32u5/m-p/784681
It requires downgrading the version of mcuboot included in the repository. The previous version was distributed without source code and prevented the integration of RSA4096 management changes into the imgtool utility.
