refactor(system): guard WDT with SoC capability macros

Browse Source 
Wrap MWDT-related code under SOC_WDT_SUPPORTED so targets without a main
watchdog can compile.

Add SOC_RTC_WDT_SUPPORTED for RTC watchdog usage (bootloader, slow-clock
paths) and regenerate Kconfig.soc_caps.in. Bootloader RWDT setup stays
under SOC_RTC_WDT_SUPPORTED; MWDT flashboot teardown stays under
SOC_WDT_SUPPORTED.

ESP_INT_WDT, ESP_TASK_WDT_EN, and BOOTLOADER_WDT_ENABLE depend on
SOC_WDT_SUPPORTED where applicable. Build xt_wdt.c only when
SOC_XT_WDT_SUPPORTED. Provide no-op panic WDT helpers when
SOC_WDT_SUPPORTED is disabled.
