feat(bindings/cpp): init cpp binding

[silver-ymz]

A demo for cpp binding

We use cxx to interop between Rust and C++.

About build system, rust side still use cargo. For better integration with google test, we use cmake and ninja to build c++ code. All build scripts are written in cmake, so ninja can be replaced by make or bazel. I choose it just because it looks like faster.

Example

#include "opendal.hpp"
#include <vector>

int main() {
    auto op = opendal::Operator("memory");
    std::vector<uint8_t> data = {1, 2, 3, 4, 5};
    op.write("test", data);
    auto result = op.read("test");  // result == data
}

Exist Problem

Now I can only build static library, failed to build dynamic library.
