In current configuration, the timer task (the one from FreeRTOS) has the lowest priority (0). Both display and system tasks are also set on priority 0. 

In cases where any other task takes too much time to execute (it can happen in Display Task, see https://github.com/InfiniTimeOrg/InfiniTime/issues/825), the timer task does not have the opportunity to run fast enough to detect and debounce presses on the button.

This commit sets the following priorities:
 - [0] : Display  Task
 - [1] : Timer and System tasks
 - [2] : BLE Host
 - [3] : BLE LL

This way, we ensure that button presses will always be detected, even if the rendering of the display takes a huge amount of time.
