The current status:
* We can't use old packages that depend on `vs2015_runtime<14.16` on
conda-forge for Python 3.9 on Windows.
Because Python 3.9 for Windows on conda-forge depend on `vs2015_runtime
14.16.27012`:
https://anaconda.org/conda-forge/python/files/modal/info/5f8784bea58f0d0a5480e400
* We can't use recent packages that depend on `vs2015_runtime>=14.16` on
conda-forge to build wheels for Windows.
Because recent packages on conda-forge don't provide static libraries:

Ideas for the next step:
1. We use our bundle mechanism to build all dependencies instead of
depending on libraries provided by conda-forge.
2. We use other packaging system like
[vcpkg](https://github.com/microsoft/vcpkg) to collect dependencies.
I tried 1 and found that our gRPC build configuration has some problems with
Visual C++. For example:
* RE2 dependency is missing. (We need RE2 for not only Gandiva but also
Flight.)
* CMake options to find bundled zlib is wrong. (We should use
`-DZLIB_INCLUDE_DIR` and `-DZLIB_LIBRARY` instead of `-DCMAKE_PREFIX_PATH`.)
* It seems that dynamic library and static library are mixed unexpectedly:

* ...
I didn't try 2 yet.
I don't have enough time to fix this problem for now. I may work on this
again next month but others can work on this.
