Improve module compatibility

[mraerino]

Which problem is this pull request solving?

Edge Handlers will provide browser apis if they can. We should choose the browser entrypoint of any packages if it is provided.

Some modules are built for node, but can run fine on our runtime, if you provide shims.

Describe the solution you've chosen

Enable browser: true in the resolve module.

Set preferBuiltins: false so people can install their own shims if they want.

Add the node-globals and node-builtins rollup plugins.

Describe alternatives you've considered

We could require people to install shims themselves.

sounds like a good idea

Great!

[mraerino]

this actually has some bugs, because those plugins are unmaintained and use an outdated version of acorn, so you can't use es2020 syntax, which edge handlers would support ootb

@mraerino Should we create an issue around this if this is a known problem?
