stm32c0: Add ID codes for C0[5,7,9]x lines

[desertsagebrush]

Detailed description

Adds in ID codes for the STM32C0[5,7,9]x microcontroller lines. Note that this doesn't distinguish yet between the C091 and C092 lines despite them having different amounts of SRAM (36kiB vs 30kiB), as there doesn't seem to be an easy way to check that.

Tested on a STM32C071 Nucleo board.

Only got the one review note, so other than the CI failures, once that's addressed we'll be happy to approve and merge this.

[dragonmux]

LGTM, merging. Thank you for the contribution!

Cool, thanks!

But how can I get a working build with this?
CI native firmware builds fail now :(

[JohnAZoidberg]

I managed to cherry-pick this changed on top of v2.0.0, resolve the conflicts and locally build it: https://github.com/JohnAZoidberg/blackmagic/tree/stm32c071
But even there CI doesn't build.

I built it locally and it can work with blackmagic hardware and Nucleo STM32C071.

We're aware of the CI failures, and part of that is down to a .yml file for the config having not yet been updated till #2167, and the other part is because of an upstream fault on the compilers - ARM reorganised their CDN and broke the checksums on all downloads, thus the GHA block we use to get the compilers is having to do updates.

For what it's worth, you didn't need to git cherry-pick at all - just grab main and build that. It has the STM32C0 additions and a pile of extra fixes which you'll benefit from. If it doesn't fit, turn off a target family like renesas to reduce the build size.
