91841a53ff WDT: Add LL and HAL for watchdog timers
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.

490bf29767 esp32s2: fix enabling 32k XTAL clock
On the ESP32S2, rtc_clk_cal(RTC_CAL_RTC_MUX) measures the frequency
of the 90kHz RTC clock regardless of the selected slow clock
frequency. Keep track which clock is selected and pass the argument
to rtc_clk_cal accordingly.

fix clock choices
