Without this, when targeting x86, the compiler may not enable sse2
by default without -msse2 switch and therefore leaves WEBP_USE_SSE2
undefined and the SSE2 procedure won't be built.

These were picked up when matching autoconf's default checks and aren't
useful except to compare the generated config.h. Removing them speeds up
cmake, especially on windows where creating new processes is slow.

Between 3.17.0 and 3.18.2 check_cxx_compiler_flag() sets a normal
variable at parent scope while check_cxx_source_compiles() continues to
set an internal cache variable, so we unset both to avoid the failure /
success state persisting between checks.
This was fixed in 3.18.3 [1], but regressed shortly afterward [2];
currently seen with 3.20.0 installed via homebrew.

Also fix the variables: we need to check for PTHREAD_PRIO_INHERIT
and PTHREAD_CREATE_JOINABLE (not PTHREAD_CREATE_UNDETACHED) and
internally use HAVE_PTHREAD_PRIO_INHERIT and PTHREAD_CREATE_JOINABLE
(and not HAVE_PTHREAD_CREATE_JOINABLE).
cmake/config.h.in actually had the right variables.

Since
a376e7b9 Fix compilation on windows and clang-cl+ninja.
the highest level assembly flag (/arch:AVX / -msse4.1) would be applied
to all assembly files. This could result in higher level instructions
being used which would defeat the runtime cpu detection check and could
result in a crash.
With this change -m style flags are used with clang-cl as it supports
them and allows the correct level to be set. With at least Visual
Studio 12 (2013)+ /arch is not necessary to build SSE2 or SSE4 code
unless a lesser /arch is forced so these flags are avoided. This matches
the nmake build.
For emscripten only sse2 and sse4.1 are tested (NEON will succeed in
being enabled, but fail to build). This is consistent with
the current behavior added in:

- 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.

GIF find_package only locates the header and library, it doesn't fail
compile tests when detecting the version, but falls back to 3 (as of at
least cmake 3.7.2). Make sure the library links to avoid incorrect
detection when cross compiling.

This is duplicating code from compiler flag checking that was once
added (then reverted to CMake) as the problem seem to be on the
clang side as detailed in:
