All code generation logic that uses the analyzer_utilities package's
`GeneratedContent` class hierarchy is modified to use
`package:analyzer_testing/package_root.dart` to locate the `pkg`
directory in the root of the SDK repo.
This paves the way for some follow-up work in which I intend to modify
the `GeneratedContent` class hierarchy so that it tracks the locations
of all code generation targets relative to the `pkg` directory rather
than the individual package directories. That in turn should make it
easier for code generation logic to be shared between error messages
belonging to `pkg/analyzer`, `pkg/front_end`, and
`pkg/_fe_analyzer_shared`.
