[feature] Support for STM32G491 and STM32H7A3/H7B3

[jjamesson]

Dear STLINK maintainers,

We are considering using STM32G491, and STM32H7A3/STM32H7B3 in our designs.

As of now, it seems that these boards are not supported by ST tools yet. Could we expect support from your toolset for these chips in the near future? It would be very helpful.

With best regards!

@jjamesson I added support for these chips earlier (9eb81e1 and 54000d6 already in the develop branch). I had nothing to test these chips on, but everything should work. Support for the H7 and G4 series has been added previously and has been tested.

Thanks for the reply, @Ant-ON ,

You're right, I checked the /doc/devices_boards.md file (under "develop" branch) and saw that these chips weren't supported according to the list, but I didn't try the development branch myself.

Thanks,
