chore: remove api side polyfilling

[jtoar]

Note: I need to figure out the dependency situation (@babel/runtime vs @babel/runtime-corejs3, and where they should go), but I think this is the minimal set of config changes to remove polyfills for the api side. I'm happy to make more Babel changes because there's still a bit we can do to clean up our config, but one thing at a time.

What this doesn't do:

• anything to the web side
• anything to redwood packages

It only affects yarn rw build api. So how a redwood app's api side is built. The change here is: we no longer polyfill anything.

The reasoning: the api side targets a fairly predictable runtime, Node.js (and right now only two versions of it). We don't need to polyfill en-masse (and we were—we were polyfilling things that didn't need to be, like Array.includes, forEach, etc.). Moreover, what we do polyfill that's not in the versions of Node we target is esoteric and 99% proposals (see the test here). Many of those proposals are in Stage 1, Stage 0, or worse, were rejected.

I haven't looked at this properly yet Dom, just the description, but worth keeping in mind that if we have polyfills in the framework, runtime is going to have to be a dependency.

I would say let's remove the polyfills from the framework too.
