internal/telemetry: encapsulate the telemetry directory

In several places throughout tests, we set all of telemetry.{LocalDir,
UploadDir, Mode} according to the standard schema ("local/", "upload/",
and "mode").

In the interest of reducing or eliminating global state to improve
testability, introduce a telemetry.Dir type which encapsulates the
telemetry directory layout. The default layout is accessed through
telemetry.Default. This makes it easier for future components to close
over or pass around a single piece of state (the Dir). In subsequent
CLs, this will be used to make uploading more testable.

For golang/go#66003
