Fix VTOR bug when using bootloader on STM32WB 

The address of the vector table is hardcoded to the start of flash in
many, if not all, ST targets. This causes a crash in applications that
are using a bootloader.  This patch updates the board STM32WB55 so it
properly handle updating the VTOR with a bootloader.

Solution has been copied from the PR #3798.
