add function access keys to additional contracts by using multiple key stores

[petersalomonsen]

Experimenting and work in progress on what's discussed here: NEAR-DevHub/neardevhub-bos#137

Currently implementing a test case that demonstrates adding additional function access keys for another contract that the one that was originally signed in for. This is useful when logged into near.social and posting to other contracts like e.g. DevHub in order to avoid having to confirm with the wallet each time.

Here's a proof of concept demo video: https://www.youtube.com/watch?v=ocZKP2-Lxes

Hi, this PR seems to be related to the signInMulti PR #811 I left a comment #811 (comment) to explain the current status of the signInMulti in wallet-selector.

@petersalomonsen I think this PR is irrelevant at this point since NearSocial/VM#156, right? Should we close it?
