[dart2js] Adding annotator layer to kernel dump info

The Annotator appends closed-world info to the KernelDumpInfo data
(such as output unit, treeshaken status, and code size).
The annotator also processes closures (since these aren't visible to the kernel).

The general pattern is:
  * Generate lookup key from JElement node
  * Find the Kernel-generated info node with this lookup key
  * Visit JElement node
  * Annotate the Kernel info with new information

Note: Function parameter logic is incomplete
