RFR: 8311806: Class ButtonAccessibility is implemented twice

Mon Jul 10 20:45:31 UTC 2023

To avoid confusion on the os x dynamic linker side i renamed native classes from ButtonAccessibility to JFXButtonAccessibility. I will use JFX prefix down the line to avoid any confusion when running with the latest JDK that also migrated to the new a11y API.
