[feature] STM32L4Q5CG support

[ciakval]

I have an STM32L4Q5CG chip that I would like to program with st-flash.

I am using the ST-LINK V2 programmer (part of Nucleo-144 L4R5ZI board), Linux Fedora 40.

The chip seems to be recognized, but it looks like the chip information is wrong regarding SRAM size (320 KiB vs. 640 KiB) and the particular chip_id is missing in flash loader.

Version of stlink: v1.8.0-62-gbfcc1e2

$ ./build/bin/st-info --probe
