As another step toward aligning the macOS plugin API with the iOS plugin API, and with its final form, rename the plugin-related classes from FLEPlugin* to FlutterPlugin*. This makes the names of the clasess the same between iOS and macOS. Eventually they should actually merge, with annotations/ifdefs for platform differences, but for now since the macOS version uses the same method names and is simply a subset of the iOS APIs (with one to-be-stabilized method that is macOS-specific) doing the merge later won't be a breaking change. Doing this now allows for building out plugin tooling and plugin implementations on macOS without creating a growing body of code that will experience a breaking change later.
