Add Tricore options to arch list

Hello! I'd like to start the process here in adding support (whatever that might mean) for tricore-gcc. Currently I'm not able to use the settings.arch to specify the actual arch I'm using, and I assume this probably goes a bit deeper than just updating the yaml file.

For the most part I'm building my firmware by hook and by crook without this support. But It would be nice to learn how to do things properly.

Unlike some other proprietary toolchains that target Aurix devices, tricore-gcc can be built yourself: https://github.com/EEESlab/tricore-gcc-toolchain-11.3.0

I already have a Conan package for this which I'm using, but it's held together with duct-tape and wishful thinking still.
