This PR fixes issue #298. I am attempting to build Carbon using Bazel on Windows, without the need to go through WSL. This is still a work in progress, below is a list of issues I have discovered and my fixes for them. - Windows does not support Homebrew; however, I was able to properly install all of the required packages through [Chocolatey](https://chocolatey.org/). This was my first time using the Chocolatey package manager, yet it was fairly easy to use. I believe there are other options as well for Windows. - As is mentioned in issue #298, your Windows installation must be running in [Developer Mode](https://docs.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development). This will allow unprivileged users to create symlinks during the build process. - As it currently stands in trunk, clang_configuration.bzl will fail when attempting to run the method `_compute_clang_cpp_include_search_paths` on Windows. I have discovered that this is because Clang++.exe fails to execute if you provide it with an input file that does not exist. Thus, I have the build script generate an empty temp file in the Bazel repo for Clang to use when running the above method. - A cc toolchain specifically for Windows was created in clang_toolchain.BUILD. I simply mimicked what was done for other platforms, I apologize if this is incorrect since I am fairly new to Bazel. As I understand it, the next step is to configure clang_cc_toolchain_config.bzl to support the new Windows toolchain. I intend to continue working on this, however as I stated I am quite new so help is seriously appreciated! Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
