[epic] devEngines

[wraithgar]

Overview

Implement the spec at openjs-foundation/package-metadata-interoperability-collab-space#15

The Plan

Because this has a complete overlap with existing checks we do for installs, npm-install-checks will still be where this logic lives. It will be changed to expect the data in this new format, and things that currently call it will conform their existing calls to that format. Then npm itself can also directly ask npm-install-checks passing it devEngines

The Tasks

Beta Give feedback

1. add functionality to npm-install-checks
2. move npm-pick-manifest over to new format of data
3. have npm install et al pass devEngines and react accordingly
4. docs
5. add libc to package.json docs in cli docs(package.json): add libc field cli#7822
6. feat: add devEngines types#85
   +0
7. Make sure engines is still used in global install if devEngines is present

My understanding is that npm won't implement the download field, and it's not clear if it will implement onFail either - if so, which enum values will it support?

[wraithgar]

It's not clear cause no code has been written. Please be patient.

I just mean the plan isn't clear, no rush tho :-)
