Add a stub file to object only library targets.
https://cmake.org/cmake/help/v3.18/command/add_library.html#object-libraries
Some native build systems (such as Xcode) may not like targets that have
only object files, so consider adding at least one real source file to
any target that references $<TARGET_OBJECTS:objlib>.

- Add `-msimd128` to flags to actually enable WebAssembly SIMD
when performing SIMD detection. It's currently required in
addition to `-msse*` / `-mfpu=neon` flags which only perform
translation of corresponding intrinsics to Wasm SIMD ones.
See a discussion at emscripten-core/emscripten#12714 for
automating this and making easier in the future.
- Remove compilation branch that prevented definitions of
`WEBP_USE_SSE` and `WEBP_USE_NEON` on Emscripten even when
SIMD support was detected at compile-time.
- Add an implementation of `VP8GetCPUInfo` for Emscripten which
uses static `WEBP_USE_*` flags to determine if a corresponding
SIMD instruction is supported. This is because Wasm doesn't
have proper feature detection (yet) and requires making separate
build for SIMD version anyway.

add some missing dependencies and convert utility libraries to
static only libraries to avoid creating unnecessary shared object
libraries which may fail to link due to missing symbols.

Stick to the strict necessary for running webp_js,
and avoid building sub-lib or examples with heavy dependencies.

Define macros in examples/unicode.h to use Unicode argv
on Windows. Keep char everywhere on Unix since it handles
UTF-8 without any change.
Impact:
- All fopen () and SHCreateStreamOnFile(),
- All fprintf() printing file paths,
- All strcmp() used with "-",
- File path parsing,
- Gif reading.
Concerned executables from examples/ and extras/:
anim_diff, anim_dump, vwebp, vwebp_sdl,
cwebp, dwebp, gif2webp, img2webp,
webpmux, webpinfo, webp_quality, get_disto
When compiled on Windows with Unicode enabled, webpmux and
img2webp will not work when used with an argument file and
will print "Reading arguments from a file is a feature
unavailable with Unicode binaries."

so add a space after the first one to keep it.

Instead of unsetting WEBP_BUILD_GIF2WEBP,
disable it to keep it displayed in ccmake.
Disable WEBP_BUILD_GIF2WEBP before it's tested.
Do the same for WEBP_BUILD_ANIM_UTILS.

It is still redefined, but to the same constant,
hence no more warning as mentioned on BUG=webp:358

add a check for cpu-features.h and rework some of the ifdef's around
android + neon. for android builds with cpu-features enabled the
*_neon.c files will still need to be flagged correctly (with e.g.,
.c.neon in Android.mk) to properly build them.

The goal is not to replace our autotools configuration, but to
provide a minimal CMake file that can build the lib, cwebp and
dwebp.
