Bug 890 - Fix GLES3 Profile Mapping, i.e. GL2ES2 queries and mappings; Validate isGLES*() usage and definition ; Add and use ShaderCode.createExtensionDirective(..)

- Fix GLES3 Profile Mapping, i.e. GL2ES2 queries and mappings
  - GLProfile: Add GL2ES2 -> ES3 mapping
  - EGLContext: Reuqest major '3' for ES3
  - EGLGLCapabilities/EGLGraphicsConfiguration: Consider EGLExt.EGL_OPENGL_ES3_BIT_KHR

- Validate isGLES*() usage and definition
  - Fix BuildComposablePipeline's isGLES() code

  - For GLSL related queries use isGLES() instead of isGLES2(),
    which would exclude ES3

- Add and use ShaderCode.createExtensionDirective(..)
  - Supporting creating GLSL extension directives while reusing strings from GLExtensions

- Minor cleanup of GLContextImpl.setGLFuncAvail(..)
