Reset the watchdog back to the initial state before enabling the
expiry interrupt. This prevents the watchdog expiring immediately if
there is a long gap between `wdt_install_timeout` and `wdt_setup`.

default watchdog initialization disable counting in EM1, EM2 and EM3
modes. If user use the WDT_OPT_PAUSE_IN_SLEEP flag via the watchdog api,
all 3 EM modes must take this flag into account to avoid wdt count
being frozen if we don't want to.

The correct procedure to reload the T0 timer is:
1. Load TWDT0 register with the new value or write 1 to RST bit in
T0CSR register to load the old value.
2. Wait until RST bit in T0CSR register becomes 1.
3. Wait until RST bit in T0CSR register becomes 0.
The current watchdog driver misses step 2.
Fix the issue in this commit.

In order to ensure that watchdog channels are freed in proper
driver state, synchronization in form of simple loop needs
to be added after stopping. In no irq variant, it is already done
on nrfx level. NRFY function can be replaced by NRFX one in
the future.

Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
