Add CMake script and batch file to download Windows bison dependency

LegalizeAdulthood · LegalizeAdulthood · commit 73f2070162a1 · 2025-01-23T10:39:24.000-07:00
The CMake script downloads and unpacks the ZIP file.
The batch file invokes the CMake script and adds the unpacked bin
directory to the path.  The path addition is necessary because bison
expects m4 to be in the path.
