dsp/lossless*: use WEBP_RESTRICT qualifier

Browse Source 
lossless_enc: better vectorization, most benefits seen in AddVector/Eq
              w/ndk r27/gcc-13/clang-16
lossless: minor reordering and some improvement to PredictorAdd5_SSE2
          w/gcc-13

This only affects non-vector pointers; any vector pointers are left as a
follow up.
