Fix antlr4-cpp-runtime VERSION filename collision on Windows

On case-insensitive filesystems (Windows), antlr4-cpp-runtime's VERSION file collides with C++ standard library <version> header, causing build failures. Adding powershell-based patch_win_cmds to correctly rename it inside Windows Kokoro builds.

Also, fix syntax errors introduced in the previous commit.
