HiDPI: Revise AWT GLCanvas/GLJPanel ScalableSurface: No setSurfaceScale(), have AWT toolkit define pixelScale only (simplification)

This aligns with Glenn's initial AWT patch commit e5e7514d649cd7dd28bbb8e04b72338dc09c2c83, i.e. removing redundancies...

Tested on Linux, Windows and MacOS w/ GLCanvas, GLJPanel and GLWindow using pixelScale values:
- Linux: 1, 2
- Windows: 1, 1.25, 2
- MacOS: 1, 2
