Add a core profile file selector to OpenGL ShaderEffect

Similarly to what we do with "hlsl" in the D3D12 backend, we can use
"glslcore" to provide a file-based alternative to the GraphcsInfo or
OpenGLInfo-based conditions in the fragmentShader and vertexShader
properties. This is particularly useful in a few places inside Qt,
for example Quick Controls, that have to cater to all possiblities.
