[vcpkg] Download vcpkg.exe rather than building it in bootstrap on Windows. (#15474)

This reduces bootstrap cost for Windows customers, resolving the issue initially submitted as #12502 .

The `toolsrc` tree was extracted to https://github.com/microsoft/vcpkg-tool. `bootstrap.sh` was changed to download the right source tarball, extract, and build it. This was chosen over the previous attempt, a submodule, over concerns of accidentally destroying people's local modifications.
