This wraps analyzer and analysis_server access to `Platform` with a
`PlatformInfo` class that has a top-level `const platform`.
With this package analyzer and analysis_server will not access
`Platform` directly anymore. But instead, to access say
`Platform.lineTerminator` we'll import `package:analyzer/src/util/platform_info.dart`
and use `platform.lineTerminator`.
We probably could add tests to prevent accidental re-introduction of `Platform` usage.
But the idea is to have a client side dartpad _compilation environment_ that is compiled
and tested inside the SDK repository. Once that lands, re-introduction of `Platform`
would cause those tests to break.
See go/clientside-dartpad for motivation.
