For the flash driver, the base address is the MCU internal flash
address (usually 0x8000000). This PR gets the that address
from the device tree node "st,stm32-nv-flash"
instead of relying on the CONFIG_FLASH_BASE_ADDRESS
which might differ when building for another flash memory.

Most implementations have the same logic, with only a different write
block size. Now that we are using write-block-size from the device tree,
it is possible to use a default implementation that can be overridden if
necessary.

On stm32g0, stm32g4, stm32l4, stm32l5, stm32u5,
and stm32wbx, it is allowed to write a zeroed dword
on unerased flash.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

This commit fixes sporadic kernel panics when writing big data chunks
to the flash. (data bus errors). Just like the stm32g4 does.

When building flash shell sample we get:
flash_stm32wbx.c:23:10: fatal error: shci.h: No such file or directory
23 | #include "shci.h"
Fix this by adding ifdef protection around inclusion of shci.h.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

FLASH_TYPEERASE_PAGES is null and doesn't represent a bit in the
register, thus this instruction has no effect.
It must be replaced by FLASH_CR_PER which is the bit that should
be cleared.

In case of control register lock, driver should return the error
immediately. Otherwise, error is later overwritten by
'rc = flash_stm32_wait_flash_idle(dev);'

move misc/__assert.h to sys/__assert.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
