Fix Bug 590: Wrong GL2 and GLES2 aliasing of GL_ARB_half_float_pixel/GL_ARB_half_float_vertex and GL_OES_texture_half_float extensions

We mistakenly aliase the GL2 and GLES2 extensions:
   - GL_ARB_half_float_pixel
       - GL_HALF_FLOAT_ARB      0x140B
   - GL_ARB_half_float_vertex
       - GL_HALF_FLOAT          0x140B

   - GL_OES_texture_half_float extensions
       -  GL_HALF_FLOAT_OES 0x8D61

This also leads to adding GL_HALF_FLOAT_OES
to com.jogamp.opengl.util.GLBuffers.sizeof(..).
