QOpenGLShaderProgram::setAttributeBuffer incorrectly calls glVertexAttribPointer on desktop with integer/double types

When passing in for e.g. GL_INT to setAttributeBuffer(), QOGLShaderProgram should call glVertexAttribIPointer(). Similarly 64-bit types should call glVertexAttribLPointer(). However, QOGLSP always calls glVertexAttribPointer leading to incorrect behaviour on desktop OpenGL.
