Enable --install-exit-handlers by default

Enable `--install-exit-handlers` by default and deprecate the option: Image size increase is negligable (10 types with 53 mehtods), and there is only 2.5% extra starup instructions (68498) for "Hello, World!" on Linux.

 `java.lang.System#setSecurityManager(SecurityManager)` invoked with a non-null argument throws a `java.lang.SecurityException` if `-Djava.security.manager` is set to anything but `disallow` at program startup.
 
-### Signal Handlers
-
-Registering a signal handler requires a new thread to start that handles the signal and invokes shutdown hooks.
-By default, no signal handlers are registered when building a native image, unless they are registered explicitly by the user.
-For example, it is not recommended to register the default signal handlers when building a shared library, but it is desirable to include signal handlers when building a native executable for containerized environments, such as Docker containers.
-
-To register the default signal handlers, pass the `--install-exit-handlers` option to the `native-image` builder.
-This option gives you the same signal handlers as a Java VM.

 ### Class Initializers
 
 By default, classes are initialized at run time.

@@ -16,6 +16,7 @@ This changelog summarizes major changes to GraalVM Native Image.
     1. `run-time-initialized-jdk` shifts away from build-time initialization of the JDK, instead initializing most of it at run time. This transition is gradual, with individual components of the JDK becoming run-time initialized in each release. This process should complete with JDK 29 when this option should not be needed anymore. Unless you store classes from the JDK in the image heap, this option should not affect you. In case this option breaks your build, follow the suggestions in the error messages.
 * (GR-63494) Recurring callback support is no longer enabled by default. If this feature is needed, please specify `-H:+SupportRecurringCallback` at image build-time.
 * (GR-60209) New syntax for configuration of the [Foreign Function & Memory API](https://github.com/oracle/graal/blob/master/docs/reference-manual/native-image/ForeignInterface.md)
+* (GR-64787) Enable `--install-exit-handlers` by default and deprecate the option: Image size increase is negligible (10 new types and 53 new methods), and there is only 2.5% extra startup instructions (68498) for "Hello, World!" on Linux.
 
 ## GraalVM for JDK 24 (Internal Version 24.2.0)
 * (GR-59717) Added `DuringSetupAccess.registerObjectReachabilityHandler` to allow registering a callback that is executed when an object of a specified type is marked as reachable during heap scanning.
