Make the build pipeline that creates a directory more resilient if the build directory already exists. (#1223)

* Add contents from a build directory.

* Use the -p option to avoid failing if the directory already exists.

* Remove the build directory from check-in.

* Revert change to .gitignore.

* Update .gitignore to exclude the VS default out directory.

* Move the out directory gitignore with the rest of the VS artifacts.
