utils: switch deps from stablelib to noble

[paulmillr]

This has been discussed in https://github.com/orgs/WalletConnect/discussions/4035.

noble is:

• audited (more audits coming soon)
• faster
• smaller
• used by other libraries (ethers, metamask), which can make them reuse same noble deps
• popular, issues will be discovered faster

Second part of the change: WalletConnect/walletconnect-utils#185

Thanks for the PR!

Can we do a test to ensure that the keys are definitely compatible between these two libraries so we don't break any existing sessions when the library is upgraded?

[paulmillr]

@chris13524 can you clarify how you want the tests to look like? Should I manually create a key with old lib and put it into new impl?

[paulmillr]

@chris13524 ping. Can you tell what to do here:

a. Create static JSON vectors from old implementation, commit them to repo, test with new code
b. Add dependency on old implementation and cross-test random vectors

[chris13524]

@paulmillr I think of you just do a manual test showing they are interoperable that's fine. Input/output of these functions would be good, don't need to test the whole app
