Add support for invoking AOT to the Maven Plugin

Browse Source 
This commit adds an `aot-generate` goal to the Maven Plugin that
triggers AOT generation on the application. The new goal shares a
number of properties with the existing `run` goal and uses the same
algorithm to detect the main class to use.

Closes gh-30525

[[aot]]
= Optimizing Your Application at Build-Time
Spring AOT inspects an application at build-time and generates an optimized version of it.
Based on your `@SpringBootApplication`-annotated main class, the AOT engine generates a persistent view of the beans that are going to be contributed at runtime in a way that bean instantiation is as straightforward as possible.
Additional post-processing of the factory is possible using callbacks.
For instance, these are used to generate the necessary reflection configuration that GraalVM needs to initialize the context in a native image.
To configure your application to use this feature, add an execution for the `aot-generate` goal, as shown in the following example:
[source,xml,indent=0,subs="verbatim,attributes",tabsize=4]
----
include::../maven/aot/pom.xml[tags=aot]
----
As the `BeanFactory` is fully prepared at build-time, conditions are also evaluated.
This has an important difference compared to what a regular Spring Boot application does at runtime.
For instance, if you want to opt-in or opt-out for certain features, you need to configure the environment used at build time to do so.
The `aot-generate` goal shares a number of properties with the <<run,run goal>> for that reason.
