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

Hello,

This pull request is related to  and , inspired by , built upon the work done in  and , and was tested on an stm32wb55rg.

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