ShaderState Usage/Test: Add setShaderState(GL) for pre-use attachment to the GL context ; GLArrayDataClient-GLSL: Check if ShaderState is attached.

ShaderState Usage/Test: Add setShaderState(GL) for pre-use attachment to the GL context
  - test cases utilize ShaderState before useProgram() was invoked,
    hence we need an API entry to attach the ShaderState explictly

GLArrayDataClient-GLSL: Check if ShaderState is attached.
  - catch error case of non bound ShaderState to GL context
