VS: Replace generation timestamp file atomically
Since commit 34c882a9 (Allow VS 7 project Rebuild and Solution Rebuild to
work, 2007-11-10) we use a "CMakeFiles/generated.stamp" and some
associated files in the build tree to avoid re-running CMake when the
inputs have not changed but VS has cleaned the outputs it knows about.
When we do not really need to re-run we restore the generated.stamp file.
The non-re-run case can happen in multiple targets in parallel in VS >= 10
so we must restore the file atomically to avoid races. Write the stamp
file to a random temporary name and then atomically rename it to the real
stamp file.
