Modifies `GeneratedDirectory.outputDirPath` and
`GeneratedFile.outputPath` to be relative to the SDK's `pkg` directory
rather than relative to the containing package. Accordingly, modifies
the `GeneratedContent` methods `check`, `checkAll`, `generate`,
`generateAll`, `output`, as well as the `DirectoryContentsComputer`
and `FileContentsComputer` callbacks, so that their first parameter is
the path to the `pkg` directory rather than the path to the containing
package.
Also modifies the `readApi` functions in `pkg/analysis_server` and
`pkg/analyzer_plugin` to accept a path to the `pkg` directory rather
than a path to the containing package, since these functions are
called by code generation callbacks.
These changes should make code generation logic easier to reason
about. They also will make it easier to move the outputs of code
generation from one package to another, which will pave the way for
some follow-up work in which I intend to start sharing error message
representations belonging to `pkg/analyzer`, `pkg/front_end`, and
`pkg/_fe_analyzer_shared`.
