Provide a new kconfig option which can be used to disable
the default seeding of the host standard library random
generator by this driver.
This allows some other component to do so without this component
default initialization interfering.

Add a semaphore to protect the disable access to the RNG peripheral
when the PM is going to suspend mode.
The change does not affect other stm32 than CONFIG_SOC_SERIES_STM32WBX
or CONFIG_STM32H7_DUAL_CORE

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.
Most of the changes here are scripted, check the PR for more
info.

This commit should optimize the way the device is allowed
to enter the suspended state. Instead of returning a PM
error code to abort the PM process, the standby power state
is constrained as long as the device is not allowed to enter
suspension. With that approach, acquiring PD_SYS is not needed
when in PM device runtime mode.

Add a command line option which will seed the random generator
from /dev/urandom.
This can be usefull for some particular tests in which we are

but we cannot provide a different random seed from command line.

With PM, when resuming from low power mode, reenable the RNG register
clocks and check the health register. If it is not set to the desired
value, it means we exit Suspend to RAM mode, and that the RNG needs to be
reinitialized.

STM32WBA controller uses a PKA driver to perform cyphering operations
on keys. Since PKA hardware block requires RNG clock to be enabled, a
synchronization with zephyr RNG driver is needed.
Use RNG enable status to check if RNG could be switched off or needs to
be switched on.
Similarly in entropy driver, don't cut RNG clock if PKA is enabled.
