Support libc field in package.json

• I'd be willing to implement this feature (contributing guide)

Describe the user story
Some packages (SWC, sharp, @napi-rs/canvas) publish native packages for both glibc and musl. At the moment users need to install both versions, as there is no conditional differentiator as for os and cpu.

Currently yarn 3.2+ and cnpm have implemented the libc field, the npm implementation is still under discussion.

Sounds good.

One difference between the yarn and cnpm implementations is that yarn gets the LibcFamily through process.report, while cnpm gets it through the detect-libc package.

cnpm/npminstall#388

process.report is not very compatible and depends on the Node.js version, while detect-libc does not have this problem.
