WASM in CI

[cryptoquick]

• Add wasm-pack and wasm32 target to lint and test in CI.
• Add caching to most actions to speed up CI builds.
• Add features needed for wasm-pack to compile to headless chrome.

This PR does not_resolve #143, but it provides the tooling necessary to debug the issues.

Hm, this PR is actually not running my CI workflow, so I can't test it. Not sure what to do here. Maybe I have to added as a developer to the repo?

@dr-orlovsky Please also see if this is okay:
cryptoquick#1

I did that because of the error in the linter test:

I see. Since we can't update edition (pls see rationale in that PR), we have to restrict the max one_cell version to the one before edition upgrade. In fact it is a failure of once_cell maintainers which introduced 2021 edition (which is a breaking change) without major version bump

[cryptoquick]

This apparently blew up in a discussion in the once_cell crate, but I found this:
matklad/once_cell#201 (comment)
Can you try re-running my CI actions again?

[cryptoquick]

Thanks! Looks like the things I'd expect to fail on wasm to fail, except the desktop clippy lints, which I believe found legitimate issues... Can this be merged, then?

[cryptoquick]

Awesome!
