To improve compile time of WebCoreArgumentCoders.h move the templates GCGLSpan & GCGLSpanTuple into their own header to be included by implementations of GraphicsContextGL. So GraphicsContextGL.h can compile with just forward declarations, move query functions getFloat, getBoolean, et al, from GraphicsContextGL.h to GraphicsContextGL.cpp
