GitHub: add workflow to provide an openocd snapshot binaries for win32

This change could be used within OpenOCD GitHub forks.

Once workflow actions are enabled in the GitHub project, this workflow
will be run automatically on each push into OpenOCD.

This workflow will provide a neutral build of openocd for win32, then
the package will be available for download in Actions section.
Note: the artifact will be deleted after 90 day (actual GitHub rules)

If the push is a tag, the generated package will be uploaded to release
pane under the corresponding release, and it will resides forever.

The built openocd enables libusb1, hidapi and libftdi adapters,
and could be extended to cover more adapters and Oses

PS: ./contrib/cross-build.sh updated to build libftdi from source like
libusb1 and hidapi.
