wined3d: Simplify shader interface matching for SM4+ vertex shaders.
After some testing it looks like, with SM4+ on Windows:
1. Output registers have to match with input registers from the
following shader stage (register index and mask). There is no "smart"
matching of semantics like in SM3.
2. Using uninitialized varyings in SM4+ shaders doesn't give consistent
results.
That means we can simplify the relevant code quite a bit. Applications
shouldn't be able to depend on particular values for uninitialized
varyings so we can avoid explicitly initializing them.
