Find project.exec and project.javaexec calls

Project.exec, Project.javaexec and the script-level exec { } and javaexec { } are deprecated since Gradle 8.11 and removed in Gradle 9, where calling them fails. The replacement is an Exec task, an injected ExecOperations or providers.exec, depending on when it runs and what uses the result, which takes a person to decide. See the Gradle upgrade guide for more information.
