Remove Security Manager Dependency Across Platform

[m-reza-rahman]

Since Jakarta EE 12 will likely support Java SE 21 and Java SE 25, it is necessary to remove any dependency on the Java SE Security Manager across the platform and all specifications. The Security Manager will likely be gone by Java SE 24. It looks like some of this work was done in EE 11, but not all. As an example of pending work, see: jakartaee/cdi#831.
