feat(tools): add a script for printing Rust stacks' sizes

[romanz]

Following #4555 and #4696:

$ TREZOR_MODEL=T3T1 QUIET_MODE=1 make -C core build_firmware; tools/print-rust-stack-sizes.py | sort -k1 -n | tail

Should we also add it to core_firmware CI job, e.g.:

diff --git a/.github/workflows/core.yml b/.github/workflows/core.yml

Thanks for adding the script! In CI the output will probably get drowned in the rest of the logs but at least the script won't bitrot, so I'm slightly in favor of adding it.
