add cortex-m-types interrupt number trait generation

[robamu]

Generated crates need the cortex-m-types dependency. I tried to test this with https://github.com/embassy-rs/nrf-pac but I was not able to fully generate the crate with update.sh with a path installed chiptool , which failed with this error:

I was able to inspect some of the generates source files, which looked fine though. The implementation is based on the one added in rust-embedded/svd2rust#959
