Build libsharpyuv as a full installable library.

Browse Source 
Headers are installed in a "sharpyuv" subdirectory of the webp
dir, e.g. /usr/local/include/webp/sharpyuv/
Remove unnecessary dependency from sharpyuv to webp/types.h

Add SHARPYUV_EXTERN so that only symbols meant to be public
are exported.

Sharpyuv users can use the library with:

find_package(WebP)
if(TARGET WebP::sharpyuv)
  # ... use WebP::sharpyuv
endif()
