Add support for reading GLSL from files with ShaderEffect

An enabler for using file selectors instead of writing GraphicsInfo-based
conditions in the vertexShader and fragmentShader properties.

[ChangeLog][QtQuick] ShaderEffect with OpenGL now supports reading GLSL
shader sources from local files and from the resource system. Whenever a
fragmentShader or vertexShader property is a valid such URL, the value is
treated as a file specification instead of actual source code.
