Add types to key wrapping and unwrapping

[JamesJansson]

Currently, it is impossible to wrap and unwrap keys in Typescript as the algorithm parameters are not possible under the current type definitions. I have used the examples of wrap and unwrap from here:
https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/unwrapKey
https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/wrapKey

I may have gone overboard a little with including "RsaKeyAlgorithm | RsaHashedKeyAlgorithm" however the following assumes that those types are necessary:

@JamesJansson looks like you need to run npm run baseline-accept to get tests to pass.

Hey @JamesJansson - we've looking through the backlog, I've updated the PR to master (and updated baselines) but we need both a CLA and the CI is failing. Any chance you can take a look at the CLA and give me an opinion on the CI?

This PR hasn't seen any activity for quite a while, so I'm going to close it to keep the number of open PRs manageable. Feel free to open a fresh PR or continue the discussion here.
