Work towards https://github.com/dart-lang/sdk/issues/62686
`dart analyze` uses an 'analysis.setAnalysisRoots' "command" to let
the analysis server know that the user requested, for example,
`dart analyze foo` or `dart analyze foo/bar.dart`. This was not conveyed
to analyzer plugins, so analyzer plugins will always analyze the entire
context collection.
(For some reason, only files in the "analysis roots" were reported in
stdout; maybe DAS or dartdev does its own filtering on diagnostics.)
This change forwards the `setAnalysisRoots` request to DAS plugins using
a new protocol message that mirrors the one for the server.
We should not change the behavior of `analysis.setContextRoots` for
legacy plugins, so we keep sending that request as per usual. Then
we send `analysis.setAnalysisRoots` at the same time.
If we receive an `analysis.setAnalysisRoots` message, dispose and
delete references to the existing context collection, and instantiate
a new one, with the specified `included` and `excluded` paths.
