Speeds up the native assets target in the backend by

1. changing other targets `gen_dart_plugin_registrant` and
`release_unpack_ios` to do async I/O,
2. not reparsing the package config, and
3. not calling `dart pub deps --json` for 0 or 1 packages (fixed
package:native_assets_builder).

The column can get really tall, especially when there's line wrapping. This is the layout on a tablet, so on a motor g4 this column is likely going to overflow.
