Sam Rawlins 7d0a17196c DAS plugins: Add print-debugging support in Insights pages.
Work towards https://github.com/dart-lang/sdk/issues/61868

This adds a new notification type, 'PluginPrint'. There are several
fields and variables then named 'pluginPrint' or 'print', and I am
definitely open to changing these names, but this is the best one that
I thought of.

PluginPrint has three fields: The name of the plugin that printed, the
message that was printed, and the timestamp.

We wrap each plugin's AnalysisRule invocations with a zone, so that
the `print` handler can know the name of the plugin. The prints are
caught and sent to the server isolate as Notifications. The
PluginIsolate then stores the collected prints. The Plugins Insights
page can then retrieve them and display them.

Manual testing, with 1000 libraries that get new lint reported once per
file, I did not observe a negative performance impact.
