wined3d: Use a separate structure for vertex shader attributes.

Browse Source 
In D3D10 shaders input/output semantics are strings rather than predefined
types. Unfortunately, the code in vshader_get_input() can be performance
critical, depending on application behaviour. Since vshader_get_input() is
only relevant for d3d9 shaders anyway, just store the usage and usage_idx for
these shaders.
