979c0ebbcd sharpyuv: add SharpYuvGetCPUInfo
This gives a similar structure to libwebp and fixes a bug where passing
NULL to SharpYuvInit() would unconditionally set optimized function
pointers. SharpYuvInit() is left as an undocumented public function and
SharpYuvGetCPUInfo is kept private to serialize updates to the pointer.

6af8845a8f sharpyuv: prefer webp/types.h
this provides better compatibility for older Visual Studio versions;
stdint.h is a part of C99.

this is consistent with the core libwebp library:
8fbb9188 prefer webp/types.h over stdint.h

a3b68c195e Build libsharpyuv as a full installable library.
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()

29cc95ce4c Basic version of libsharpyuv in libwebp, in C.
It's self contained apart from a dependency on src/webp/types.h and src/dsp/cpu.h
For now it's only set up as an internal library, not an installable one.
Webp doesn't depend on it yet, the code is only duplicated.
