Unify Windows scripts for getting nightly binaries

The new script merges existing scripts for downloading translations and
SPIR-V shaders, and also exports game binaries from the latest nightly
build into the git repo.

This allows contributors, especially artists, to obtain a working build
of the game without learning how to build the game for Windows, refs #1814.
