Add new devicetree bindings for F4 and L1 series for configuration of
block size used in flash write operations.
Allow byte-size write operations in `flash_stm32f1x.c`. This file is
being shared between F0, F1, F3, L0 and L1 series. L0 and L1 series
allows for single byte writes.

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.

Instead of introducing a vX driver version, use series name.
With this commit F0, F1, F3, L0 and L1 series are using F1 flash driver.

Several STM32 chips have identical chip-specific code that has been
duplicated in different source files. Unify the F0x, F1x, and F3x to
use a single implementation.

Remove soc/arm/st_stm32/stm32YY/flash_registers.h files.
Change register accesses in stm32 flash drivers to use FLASH_TypeDef
from modules/hal/stm32/stm32cube/stm32YYxx/soc/stm32xxxxxx.h.
Fixes#16235
