RFR: 8310847: [Mac] Silence OpenGL deprecation warnings [v2]

[Martin Fox]

> The Mac build issues a lot of warnings including several related to the deprecation of OpenGL in macOS 10.14. Now that the deployment target for JavaFX is 11.0 across the board these warnings are showing up on both M1 and Intel builds. Luckily Apple provides a simply way to silence these warnings by setting a single C preprocessor define.
