Enable cloudflare Node.js compatibility layer

[pi0]

Cloudflare supports a subset of Node.js compatible imports.

Unenv, has a good coverage for most of the Node.js polyfills and shims. But by replacing the supported subset we can:

• Reduce bundle size as runtime provides them
• Leverage node:internal native features are impossible to add into userland such as async_hooks

There are two concerns:

• Cloudflare shims are not as complete as unenv ones
• We need to make sure wrangler.toml has enabled compatibility flag and otherwise fail or warn the build to ask users doing this based on usage.

We need to add a cloudflare preset to unenv first.

We shall find a way to inject compatible classes from platform

Hopefully this shoud resolve cloudflare/workers-sdk#2081

I can see we don't have a tracking repo on our side though, ideally try to pinpoint if its a Nuxt/Nitro/Nuxt-security issue and open an issue there 🙏🏽
