flash/nor/stm32f1x: Add support for GD32E23x

Browse Source 
GD32E23x from GigaDevice is cortex-M23 microcontroller and it can work with the stm32f1x driver.
Modifications are similar to this done for GD32F1x0 in #6164 (https://review.openocd.org/c/openocd/+/6164).
Configuration file is added because its cortex-M23 CPU ID is different.
I think that GigaDevice microcontrollers should be handled in an independent unit to separate them from STM32,
but nowadays quick solution is welcome.
