8226384: Implement a better logic to switch between OpenGL and Metal pipeline

[jayathirthrao]

We have many if else conditions to select OpenGL/Metal pipeline objects.
Apart from initialization phase we should not fetch these objects everytime checking whether we are using OpenGL/Metal pipeline.

jtreg/JCK all test run is green in both OpenGL and Metal.
Also sanity check using J2DDemo and SwingSet2 is fine.

Hi Phil,

We still have some if else checks in initialization paths like CPlatformView.initialize(), CPlatformEmbeddedFrame.initialize() and static access of RenderQueue method, like in LWCToolkit.sync().

Thanks,
Jay
