Previously, Log4j2's own shutdown hook was only disabled when Log4j2
detected javax.servlet.Servlet on the classpath and, therefore,
determined that it was running in a web application. In an application
without Servlet on the classpath, this could lead to both Log4j2's shut
down hook and and logging system's shutdown handler both stopping
Log4j2. This could result in a failure as the second attempt at stopping
would result in reinitialization which would fail as the JVM is already
shutting down.

This commit introduces a new Log4j2 PropertySource implementation,
registered via META-INF/services, that sets the
log4j.shutdownHookEnabled property to false. This will ensure that
Log4j2's own shutdown hook is disabled by default whenever Spring Boot
is on the classpath and not just in Servlet-based web applications.

Previously, a project with a dependency on Spring Boot's configuration
processor would fail to build when the configuration cache is enabled
due to it accessing the Project during task execution.

Instead of accessing the project during task execution, this commit
updates the code to retrieve the resource locations from the matching
source set in advance. The locations are then stored in the action
that configures the compile task when needed.
