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.

Rename "app" projects in `spring-boot-launch-script-tests` and
`spring-boot-loader-tests` to something unique.

Update the jar `Handler` class to support a non-reflective fallback
mechanism when possible. The updated code attempts to capture a regular
jar URL before our handler is installed. It can then use that URL as
context when creating the a fallback URL. The JDK jar `Handler` will
be copied from the context URL to the fallback URL.

Without this commit, resolving new Tomcat URLs of the form
`jar:war:file:...` would result in an ugly "Illegal reflective access"
warning.

Fixes gh-18631

Update `StandardConfigDataResource`  to make the `getResource()` method
public so that it can be used by Spring Cloud.
