vkd3d-shader: Introduce struct vkd3d_shader_parameter_info and struct vkd3d_shader_parameter1.

Browse Source 
As the newly added documentation describes, this reroll serves two purposes:

* to allow shader parameters to be used for any target type (which allows using
  parameters for things like Direct3D 8-9 alpha test),

* to allow the union in struct vkd3d_shader_parameter to contain types larger
  than 32 bits (by specifying them indirectly through a pointer).
