Fix STM32 crashes on boot due to unset VTOR
Remove HAL_Init and related code from SystemInit and move it to mbed_sdk_init. The function SystemInit is called early in the boot sequence before RAM is initialized or the VTOR is setup, so it should not be used to perform the HAL initialization. This fixes crashes due the vector table being used before it has been relocated.
