1: reduce python whl package size
2: unify api link logic on all OS
3: add option: MGE_WINDOWS_BUILD_WITH_STATIC_CRT
    --- default OFF
    --- if build CRT(vc runtime) with STATIC with megengine.dll
        some CRT api will crash, for example, flush, so if you
        build with static megengine, and do not want to install CRT
        you can set MGE_WINDOWS_BUILD_WITH_STATIC_CRT TRUE
    --- how to install CRT:
        https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-160
        install VC_redist.x64.exe
4: rename megengine_export to megengine_shared(only export needed symbols ),
   caused by runtime symbols conflict with pytorch

more detail:
```
 printf("%d\n", std::isnan(std::numeric_limits<float>::quiet_NaN()));
 printf("%d\n", std::isnan(std::nan("1")));
```

linux-clang and android-NDK clang have diff build logic with gcc and
macos/windows clang/clangcl
* clang++-12 -Ofast 1.cc
output is:

xp sp2(x86) do not support vc runtime fully, casused by KERNEL32.dll do not
implement some base apis for c++ std function, for example,
std::mutex/std::thread/std::condition_variable as a workround, we will
disable some MegEngine features on xp sp2 env, for exampe, multi-thread etc!

* about DNN_MUTEX/MGB_MUTEX/LITE_MUTEX, if your code will build in inference
code (even CPU backends), please replace std::mutex to DNN_MUTEX/MGB_MUTEX,

* about multi-thread, if you code need multi-thread support, please
enable it when MGB_HAVE_THREAD=1

* about test build env status
1: Visual Studio 2019(MSVC version <= 14.26.28801)---- pass
2: Visual Studio 2019(MSVC version > 14.26.28801) ---- failed
   caused by this 'new' version will put VCR depends on win7
   KERNEL32.DLL, this may be fixed at Visual Studio 2019 later version
   but we do not test at this MR merge point
3: Visual Studio 2017   ---------- pass

reason: some target call python3 to generate some headers,
if PYTHON_EXECUTABLE changed, headers will be invalid, which
will lead to rebuild most of obj, because this headers will
be include in most cpp/c, what`s more, this target do not depends
python3 version(python API) the output is same when use python3.5
or python3.x so change use PYTHON_EXECUTABLE to
PYTHON3_EXECUTABLE_WITHOUT_VERSION, when
PYTHON_EXECUTABLE/PYTHON_LIBRARY/PYTHON_INCLUDE_DIR changed,
can reuse the build obj
