This commit updates the watchdog timers (MWDT and RWDT) in the following ways: - Add seprate LL for MWDT and RWDT. - Add a combined WDT HAL for all Watchdog Timers - Update int_wdt.c and task_wdt.c to use WDT HAL - Remove most dependencies on LL or direct register access in other components. They will now use the WDT HAL - Update use of watchdogs (including RTC WDT) in bootloader and startup code to use the HAL layer.
