Now that both OpenGL and D3D supports files, it is trivial to add support
for file selectors. This means that one can add for example a
shaders/wobble.frag with GLSL source code and a
shaders/+hlsl/wobble.frag with D3D bytecode, while simply writing
fragmentShader: "file:shaders/wobble.frag" in QML. The rest is automatic.

Let's revise our policy of offline/bytecode only shaders. ShaderEffect
benefits greatly from having runtime compilation support for HLSL
source strings, especially when dynamically constructing shader strings.
There is no reason not to support both approaches since we rely on d3dcompiler
for reflection anyhow.
What's more, we can call D3DCompile on a dedicated thread, keeping the
gui responsive while compilation is on-going.

Rename RendererInfo to GraphicsInfo. Deprecate OpenGLInfo and move
the surface format properties into GraphicsInfo. Move also the
shader info properties from ShaderEffect.

Like when there is only one shader is given by the ShaderEffect item, or
when texture providers disappear (use a dummy texture in this case).
Changing the cull mode works now too. Fix also the inconsistent naming
(activate -> use) for textures in the glpyh cache. The cbuffer is now
correctly aligned. Filtering and wrap modes are now taken from the
texture, meaning 'smooth' and 'wrapMode' works.

D3D12 shader effect node.
Cull mode, atlas (qt_SubRect_*) support, and some nice-to-haves are
currently missing. The built-in shaders won't yet work due to not sending
'source' down the stack so both have to be application-supplied.
Nonetheless..the wobble test works!

The D3D12 node implementation is mostly missing. The rest of the enablers
should be in place now however.
Importing QtQuick 2.8 provides new properties for ShaderEffect:
- shaderType can be used to decide which language should be used
- shaderCompilationType tells if compilation is runtime or offline
- shaderSourceType tells if the vertex/fragmentShader properties refer
to source strings or source files or pre-compiled bytecode files
The last two are bitmasks. In practice however we will support only
one approach per backend for now (runtime + source string for OpenGL,
offline + bytecode for D3D12).
In addition to QSGShaderEffectNode, introduce the QSGGuiThreadShaderEffectManager
interface. This provides the gui thread bits for the above and performs shader
reflection. Backends that use the new ShaderEffect system must provide both.
For each ShaderEffect item there will be a manager (on the gui thread) and
a node (on the render thread).
Reflection is expected to be done via standard helper libs (d3d12shader
+ D3DReflect from d3dcompiler for the D3D12 backend), or via manually inspecting
SPIR-V, or parsing the source (like the GL path does now), or by using some
3rd party library (not recommended). In any case we require that reflection is
doable on the gui thread without dependencies to the actual graphics API.
The ShaderEffect documentation is greatly extended, covering HLSL and the new
properties.
The test app uses manually compiled shaders on its HLSL path for now. This
is because there is no story yet for build system integration for public
use (the internal HLSL -> bytecode in C header rule is only suitable for
the d3d12 plugin itself, apps need something different).
