build_llvm_package.bat: Build teh clang-format plugin separately

In r293373 we switched the build to linking dynamically against the
Universal CRT and include the redistributables in the installer.

However, clang-format.exe is copied into the vsix and needs to be
statically linked. This commit makes us build the plugin in a separate
step that uses static linking.
