Add a rv32im-unknown-none-elf check to CI

[Rjected]

Describe the feature

Right now we have a check_wasm script which takes in crates, and checks them for no_std compliance on the wasm target:

reth/.github/assets/check_wasm.sh

Line 100 in 6bba5e6

cmd="cargo +stable build -p $crate --target wasm32-wasip1 --no-default-features"

We need this script, but with a separate workflow and separate list of crates for the rv32im-unknown-none-elf target. This will allow projects like kona to understand which crates it can use more easily.

Additional context

No response

[mattsse]

can we also invert the list and only check included crates?

@mattsse the goal was to manually exclude a crate when you create a new one in the project, so that you're aware that your crate isn't no_std-friendly
