1. Support x_google_ignoreList in source map infra (facebook#973) …

   Summary:
   Pull Request resolved: facebook#973
   
   Changelog:
   * **[Feature]**: Basic support for `x_google_ignoreList` in `metro-source-map` and `metro-symbolicate`
   
   Enables Metro's source map infrastructure to produce and consume the `x_google_ignoreList` field, documented [here](https://developer.chrome.com/blog/devtools-better-angular-debugging/#the-x_google_ignorelist-source-map-extension).
   
   An upcoming diff will use this infra support to add ignore lists to Metro's source maps by default.
   
   The changes here include:
   
   * An option to mark source files as ignored in `metro-source-map`'s `Generator` (used by the serializer).
   * Preserving ignore lists in `composeSourceMaps`. `composeSourceMaps` is used by React Native in [OSS](https://github.com/facebook/react-native/blob/c1304d938da9cd5016da0bded4d618c42efbd7e4/scripts/compose-source-maps.js#L13) to generate source maps for Hermes bytecode compiled from Metro bundles.
   * Including an `isIgnored` field in source locations returned via the `metro-symbolicate` API. `metro-symbolicate` is the reference implementation of symbolication based on Metro's source maps.
