Add arch files and Kconfig options to interface with the progmem driver on STM32G0 MCUs. ## Summary This PR adds the ability to program and erase blocks of flash memory using the progmem interface from application code. To do this, needed to enable selecting chip flash configuration in KConfig. The interface is enabled by selecting the menu option in the system type menu. Selecting it in system type will enable the proper MTD progmem option automatically. This driver assumes non-secure memory access. Does not check for memory protection mechanisms. Similar to implementation used for STM32H5. ## Impact This change only effects the G0 portion of the `stm32f0l0g0` directory. Other architectures in this directory may share similar flash interfaces, but I did not have the boards to test them so I isolated the G0. ## Testing This was tested with both STM32G071RB (single bank) and STM32G0B1RE (dual bank) chips, on Nucleo-G071RB and Nucleo-G0B1RE boards respectively. OS: Ubuntu 24.04 Docker container on Ubuntu 24.04 host MCU: STM32G071RB and STM32G0B1RE Compiler: Arm GNU Toolchain 13.3.Rel1 (Build arm-13.24) Testing was done using a custom application, called from NSH, to write and erase flash blocks. Breakpoints where placed between each erase/write step, and the flash memory was inspected through the debugger to verify that the writes and erases occurred as expected. On STM32G071RB, the last flash erase block was tested. On STM32G0B1RE, the entire bank2 was tested. -- This is an automated message from the Apache Git Service.
