Add maximize-build-space action

This PR adds this simple magical (hacky) github action which gets us enough extra disk space to build the massive polkadot crates.

With --release

Running cargo clean && cargo nextest run --release && du -h locally shows that my Tuxedo directory totals to 11G after all tests run. That seems like it should be good enough. Maybe even enough to fit in the 14GB that we have without the magic action.

WithOUT --release
Running cargo clean && cargo nextest run && du -h locally shows that my Tuxedo directory totals to 25G after all tests run. That is more than double, but seems like it still should have fit into the magically expanded disk space.

Anyway, the CI job is running with --release now. I guess we'll see shortly.

The action did not solve the problem we had, cargo gets stuck on some windows crate.
Thanks for testing my intuition with --release and pointing out it was indeed a good solution.

cargo gets stuck on some windows crate

How did you determine that. I can't see any logs from the failed jobs. (except for the first few steps which succeeded)

I ran the action and looked at the logs in real time for 30 minutes. I don't recommend doing it.
