fix(panic_handler): Updated panic handler to use RTC WDT

This commit updates the following:
- Updates the panic handler to use only the RTC WDT to reset the system.
- Refactors some of the panic handler code.
- Updates Bluetooth files where in they now feed the WDTs instead of
  reconfiguring them.
- Removes some unnecessary configuration of WDTs from various files.
- Added a unit test to verify that the system does not lock up when the
  panic handler is stuck.
- Updates the memprot unit tests to work with the refactored panic
  handler.
