James Zern	1fe3162541	dsp/: use WEBP_HAVE_ to determine Init availability 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.
