[PATCH 4/5] wined3d: Add shader_precompile() to shader_backend_ops.

[Józef Kucia]

A shader backend can decide to precompile a shader in the shader_precompile()
function. This can be used immediately for compute shaders. In the long term we
may also consider to compile other shader types with reasonable default compile
arguments.
