Update flash 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.

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:
sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

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.

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.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Also replace some
config
prompt "foo"
bool/int
with the more common shorthand
config
bool/int "foo"

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.)

FLASH_SIMULATOR is defined in drivers/flash/Kconfig.simulator, which is
source'd within an 'if FLASH' in drivers/flash/Kconfig.

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.

This commit adds the default configuration to the flash_simualtor
to allow unaligned reads.
Disable this option when testing to increase test coverage.

This commit adds a flash driver implementation that writes to RAM and
exports statistics through stats.h. It can be used to simulate flash
memory for testing purposes.
