Update `ConfigDataEnvironment` so that the `Binder` is registered as
a prototype bootstrap instance. This allows it to be accessed early
but still replaced when a more complete version is available.

Fixes gh-24559

Update `BootstrapRegistry` so that it can be used to register instances
in either a `singleton` or `prototype` scope. The prototype scope has
been added so that instances can be registered and replaced later
if needed.
