Build lib/_internal/analysis_summary during SDK build.

We cannot commit this CL right now, because we will attempt to use
these summaries by default, and they are incomplete yet. But I wanted
to see how to add something to the build process, and we might do
changes to make using SDK summaries optional initiallyand then commit
this CL.
