Ideally what we do with browserPerformanceTimeOrigin is to make this timeOrigin calculation more generic for browser/node, I generally think it uses a good heuristic to determine timeOrigin reliability.

Can we make this a new type instead of this type cast?

I think it's fine to keep esp because it's only being used here.

This PR removes the usage of `dynamicRequire` from `packages/utils/src/time.ts` and cleans up our timestamp code to be simpler and reduce bundle size. Removing `dynamicRequire` means that we no longer rely on `perf_hooks` for the `performance` API, but instead try to grab it from `globalThis.performance`. `performance` was added to the global in Node 16, which means we'll fallback to using `Date.now()` in Node 8, 10, 12, 14 (and in v8 just Node 14). I think that is an acceptable tradeoff, we just reduce accuracy for those versions. This does not refactor `browserPerformanceTimeOrigin` code at the bottom of the file, I want to come back and touch that in a follow up PR to reduce the amount of changes made here. I would appreciate reviews/opinions on this, I'm not 100% confident in the changes.
