add node-pre-gyp support

[b-ono]

This PR modifies electron-rebuild to use node-pre-gyp if the binary section is present. It uses the --fallback-to-build option to build the dependency if no prebuild binary is available.

[MarshallOfSound]

Can you explain exactly what this achieves, as far as I am aware node-pre-gyp is 100% incompatible with Electron binaries and this fallback-to-build is semantically equivalent to our existing node-gyp logic?

[b-ono]

node-pre-gyp can build the packages for electronif the runtime and disturl and so on is specified correctly. It can also download the prebuild packages from the specified host.

fallback-to-build should be equivalent to the existing node-gyp logic.

[MarshallOfSound]

As far as I am aware node-pre-gyp --fallback-to-build is just a complicated wrapper around node-gyp and this module actually exists to fix numerous issues with using node-pre-gyp so I'd like to avoid using it.

If this PR actually fixes a bug please raise that as an issue and we can look at solving it without bring in the pre-gyp dependency

@MarshallOfSound node-pre-gyp is very useful when the module already has binary pre-build. for example, use electron with realm-js which has:

  "binary": {
    "module_name": "realm",
    "module_path": "./compiled/{node_abi}_{platform}_{arch}/",
    "host": "https://static.realm.io",
    "remote_path": "/node-pre-gyp/{version}/"
  }

so node-pre-gyp will download it from
https://static.realm.io/node-pre-gyp/2.29.2/realm-v2.29.2-electron-v4.2-win32-x64.tar.gz.
This tar.gz only include a single file realm.node already pre-build.

please consider add node-pre-gyp support. Because electron-forge depend on electron-rebuild but electron-rebuild not support node-pre-gyp.
