dsp/*: use WEBP_HAVE_* to determine Init availability

Browse Source 
after:
  ece18e55 dsp.h: respect --disable-sse2/sse4.1/neon
WEBP_USE_* will be set when a module is targeting a particular
instruction set, e.g., sse4.1, and not overridden if WEBP_HAVE_SSE41 is
set, as previously this would ignore the case where the instruction set
was disabled via config.h and the HAVE macro was unset.

dsp.h not ensures WEBP_HAVE_* are set when WEBP_USE_* to cover cases
where the files are built without config.h.
