Add Windows and CMake support

[glywk]

This update purpose many improvements:

• add windows support.
• add cmake support to build serdes and serdes++ static libraries. Option build are detailed in Readme.md.
• separate tinycthread build in another static library to avoid multiple definition conflict when libserdes is linked with librdkafka.
• fix memory access violation if custom schema handle is not HandleImpl based.

CMake Error at CMakeLists.txt:19 (find_package):
By not providing "Findlibavrocpp.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"libavrocpp", but CMake did not find one.

Could not find a package configuration file provided by "libavrocpp" with
any of the following names:

libavrocppConfig.cmake
libavrocpp-config.cmake

Add the installation prefix of "libavrocpp" to CMAKE_PREFIX_PATH or set
"libavrocpp_DIR" to a directory containing one of the above files. If
"libavrocpp" provides a separate development package or SDK, be sure it has
been installed.

Hi,
Thanks for your answer. To install and generate all libserdes CMake dependencies, I have purpose a Conan based solution. You can see the command line example for Windows in the README.md.

cd build
conan install -pr:b win_x86_64_release -pr:h win_x86_64_release ../conan/conanfile.txt
cmake .. --toolchain=conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release
cmake -P cmake_install.cmake```

Regards
