Enhance Bootsrapping of JOGL around 37% - 40% (1st start in new JVM) - GLProfile and GLContext*

GLProfile: Enhance bootsrapping performance of loading GL*Impl class
  - Offthread classloading of all GL*Impl via reflection at startup
    reduces startup time here around 12% (800ms down to 700ms).

GLContext*: Enhance bootsrapping performance of querying available GL profiles
  - Add PROFILE_ALIASING mode, defaults to true - can be disabled w/ property 'jogl.debug.GLContext.NoProfileAliasing'
  - PROFILE_ALIASING:
      If true (default), bootstrapping the available GL profiles
      will use the highest compatible GL context for each profile,
      hence skipping querying lower profiles if a compatible higher one is found.
        Linux x86_64 - Nvidia: 28%,  700ms down to 500ms
        Linux x86_64 - AMD   : 40%, 1500ms down to 900ms

- GL*Impl:
  - make fields final: glProfile, _context, buffer*Tracker and glStateTracker
  - allow null _context/glProfile in initialization (bootstrapping)

- JoglVersion.getDefaultOpenGLInfo(..)
  - add arg: 'boolean withCapabilitiesInfo', allowing to suppres the list of caps
