meta-agl-flutter: add agl-flutter-env

Add agl-flutter-env recipe that installs a /etc/default/flutter
environment file that can be sourced to get the default Flutter
version and runtime type.  The variable AGL_FLUTTER_DEFAULT_RUNTIME
can be overridden at build time to switch the default runtime from
release to something else.
