chore: sync external contributions (#6984)

This is a workaround for CI not triggering secrets on external PRs. In
the future we should perhaps automate this.

Features:
```
fix: Use Date.now() in case performance.now() is undefined (#6982)
It seems like `performance.now()` used in `foundation/timer.ts` isn't
supported in specific environment, such as certain browser extension
apps, web workers, embedded browsers, etc... In my case, Metamask's Snap
server app doesn't support it, causing an error in initiating a
transaction. I [patched
it](https://github.com/porco-rosso-j/aztec-snap/tree/0.41.0/patches) but
thought it'd be good to add the fix here as other developers might face
it.

This PR doesn't replace `performance.now()` but lets Timer class's
methods switch to use `Date.now()` when `peformance` is undefined.
