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.

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.

Now that all watchdog drivers support DTS we can move setting of
HAS_DTS_WDT to the global watchdog symbol instead of per driver.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

- Add WDT(0,1) to esp32.dtsi
- Extend the module to be able to use WDT(0,1)
- Some minor refactoring due to usage of device tree
Tests:
- samples/drivers/watchdog
- tests/drivers/watchdog/wdt_basic_api
Note:
- timer module interrupt registers shall be removed when
timer driver implemented.

Each driver seemed to use their own Kconfig option to set the name for
their drivers. This makes writing example/test code difficult as each
one of them will have to special case for each of the supported
platforms.
Use a consistent CONFIG_WDT_0_NAME option in all drivers.
Fixes#8094.

Instead of relying on CONFIG_WDT_ESP32_DISABLE_AT_BOOT, use
CONFIG_WDT_DISABLE_AT_BOOT that's available for all watchdog timers.

Zephyr's watchdog API is badly designed in the sense that it's a 1:1
abstraction on top of whatever Quark D2000 expects for its watchdog,
instead of expecting a generic timeout value.
This implementation tries as much as possible to calculate the watchdog
timeout in a way that's compatible with a Quark D2000 running at 32MHz;
a comment in adjust_timeout() explains this in more detail.
