Refactor the part of the flash simulator that interacts with the
host when build for native platforms, so it is possible to use
it also with the embedded libCs.

Add the ability for the flash simulator to store its contents in a
memory region.
This allows filesystems on the flash simulator to survive a reboot.
And allows subsystems (e.g. coredump) to store their info on ram while
using the (existing) flash partition backend.
Add a example (for nucleo_f411re) that shows how to configure the flash
simulator for hardware (cfg discussion #54166).

For the POSIX architecture, add options to:
* Clear the flash content at boot
* To delete the file on exit
* To just keep the flash in RAM instead of a file in disk

MISRA C:2012 Rule 14.4 (The controlling expression of an if statement
and the controlling expression of an iteration-statement shall have
essentially Boolean type.)
Use `do { ... } while (false)' instead of `do { ... } while (0)'.
Use comparisons with zero instead of implicitly testing integers.

In order to bring consistency in-tree, migrate all drivers to the new

Refactors all of the on-chip flash drivers to use a shared driver class
initialization priority configuration, CONFIG_FLASH_INIT_PRIORITY, to
allow configuring flash drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers.
Driver-specific options for SPI-based flash drivers are left intact
because they need to be initialized at a different priority than on-chip
flash drivers.

So fare flash simulator had been forced to use the statistic
subsystem.
This patch introduces CONFIG_FLASH_SIMULATOR_STATS which allow to select
whether the statistic is involved in flash_simulator operations.
This patch allows to reduce flash footprint when the statistic is
not required.

For getting the address of the RAM region in the application we need to
extend the api for the flash_simulator.
This path introduce flash_simulator_get_memory() call which allow to
do so.

The change is done to avoid redefinition errors while attempting
to enable flash_simulator with stm32 platform (stm32f4_disco)
which exports its own definition of FLASH macro, from stm32f407xx.h.
Unfortunately the stm32 definition is visible within flash_simulator
via inclusion of device.h.

flash_write_protection_set() API was deprecated so driver
implementation interface is left behind as well.
This patch removes all implementation pointed by the interface

Flash write protection services were integrated into erase and write
procedures. This is step required for fixing following issue:
Multi-threading flash access is not supported by
flash_write_protection_set().
flash_write_protection_set() will be deprecated
As CONFIG_FLASH_SIMULATOR_ERASE_PROTECT become a dead option.
this commit removes it as well.

With addition of flash_parameters structure, and supporting API call
to retrieve it, it is no longer needed to store write_block_size as
a part of flash_driver_api and it should be part of flash_parameters.

After startup the native_posix flash was filed by 0x00 instead
of 0xff, which is not coherent with erased byte value which
is 0xff for the native_posix target.
Such inconsistent behavior makes for instance running
a storage system designed(or configured) for a flash device
with 0xff as erased byte values problematic.
This patch makes flash erased after new flash device file creation.

Flash size calculation was don with assumption that flash page size
is always 1 KB and flash size was parameterized with such granularity.
This patch correct this bug.
Flash pages number under statistic can't be calculated via preprocessor
anymore - thus are parameterized via Kconfig.
