wined3d: Explicitly pass the texUnitMap to shader_glsl_load_vsamplers() and shader_glsl_load_psamplers().

[Henri Verbeet]

The general idea here is to reduce dependencies on the entire stateblock, and
pass the real dependencies explicitly. This should make it clearer what
context a shader really needs.
