Description
The sun.misc.Unsafe access memory methods have been deprecated for removal by JEP 471 as of JDK 23.

We need to add `@SuppressWarnings("removal")` annotations to all MarlinFX classes that use sun.misc.Unsafe.

Longer term we need to replace our usage of these methods. See JDK-8334137.

I attached a log file with the warnings. It was generated by enabling "-Xlint:removal", setting `jfx.jdk.target.version=23`, and building using a recent JDK 23 ea.

I did a preliminary prototype of this while testing the implementation of JEP 471, JDK-8331670. The easiest thing to do is to annotate all top-level Marlin classes that access sun.misc.Unsafe. If it's not too much extra work, I might try to do more fine-grained annotations.
