1457: TL Mbox read and write for stm32wb r=xoviat a=OueslatiGhaith

Hello,

This pull request is related to #1397 and #1401, inspired by #24, built upon the work done in #1405 and #1424, and was tested on an stm32wb55rg.

This pull request aims to add read and write functionality to the TL mailbox for stm32wb microcontrollers
