When the CONFIG_WDT_DISABLE_AT_BOOT is not set, the iwdg
should be configured by iwdg_stm32_install_timeout
and started by iwdg_stm32_setup

To follow the IWDG configuration sequence, the timeout install is
just preparing the reload and prescaler parameters.
Then during the iwdg setup the watchdog is enabled and configured
at the same time.

the watchdog is enabled by the wdt_setup()
coming after the wdt_install_timeout.
Due to PR #44972, the code did not follow that.
This PR fixes the correct other in the sequence.

In the function iwdg_stm32_install_timeout, the test on watchdog ready
was inverted. So, if 2 successive calls were made to this function, the
value of the prescaler or counter reload was not taken into account.

Convert watchdog drivers to use new DT variants of the DEVICE APIs.
DEVICE_AND_API_INIT -> DEVICE_DT_DEFINE
DEVICE_GET -> DEVICE_DT_GET
DEVICE_DECLARE -> DEVICE_DT_INST_DECLARE
etc..

CONFIG_IWDG_STM32_TIMEOUT allowed values of 100 us for initial watchdog
timeout, which was actually rounded to zero in the driver, which uses
milliseconds resolution for timeouts. This resulted in the reload value
being set to maximum possible (calculation: 0U - 1).
This commit updates the calculation of timeout minimum and maximum
values considering the actual LSI frequency of the used MCU.
As the resolution of CONFIG_IWDG_STM32_TIMEOUT in microseconds doesn't
make sense if the driver supports only milliseconds, it is renamed to
IWDG_STM32_INITIAL_TIMEOUT (this prevents accidental wrong settings in
existing firmware) and the unit is changed to ms.

Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce
flash footprint.

This patches add a delay after setting the watchdog

iwdg_stm32_install_timeout expects a timeout passed in
milli seconds. As the timeout is defined in micro
seconds in Kconfig.stm32, we need to divide by
USEC_PER_MSEC when CONFIG_IWDG_START_AT_BOOT is
activated because iwdg_stm32_install_timeout makes
the multiplication by USEC_PER_MSEC.

move watchdog.h to drivers/watchdog.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Basically, all driver file names should start with the driver type as
prefix: wdt_ in case of watchdogs here.
Maybe 'iwdg' keyword could be removed entirely, and also in function
names. However that is not the scope of this patch.
