This allows Fuchsia components executed by the Flutter runner to specify a directory containing assets if they wish to store assets separate from program data. This is specified in the program metadata field within the component's specification with the new "assets" attribute. If this attribute is absent, assets are loaded relative to the path specified in the "data" attribute as before. This is useful in the short term to use a location in the package where we can store small files more efficiently. It is also potentially useful longer term to enforce a stronger separatation between executable program data and non-executable assets. This commit adds some basic unit testing for the data parsing to the flutter_runner_tests suite.
