[BSP][RIGv2] Enable up to 12 servos for the Orion project

* Remove usage of TIM5 (used by Miosix)
* Introduce usage of TIM2 (previously used by TimestampTimer, not the case anymore since the update to Miosix 2.7)
* Repurpose unused sensor CS pins to additional timers

Some servos will now share the same timer (but different channels), meaning the same frequency must be used for such cases.
