Introduce a hidden Kconfig option named HAS_WDT_DISABLE_AT_BOOT and
allow users to enable WDT_DISABLE_AT_BOOT only when that hidden option
is selected by a watchdog driver, i.e. disabling at boot is supported.
Select this new hidden option for all existing watchdog drivers that
refer to WDT_DISABLE_AT_BOOT.

In the current driver, the longest time of the watchdog timeout is ~8
seconds because the pre-scalar is fixed at 32 (WDCP=5). This commit
removes this limitation by dynamically calculating the pre-scalar
according to the watchdog timeout setting from the API.

Update watchdog drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

In npcx7 series, the Timer and Watchdog module (TWD) generates the
clocks and interrupts used for timing periodic functions in the system.
It also provides watchdog reset signal generation in response to a
failure detection.
The CL also includes:
— Add npcx watchdog device tree declarations.
— Zephyr watchdog api implementation.
— Add Watchdog definitions for npcx7 series in
tests/drivers/watchdog/wdt_basic_api/src/test_wdt.c for
supporting test suites.
