Linux: Use NSIS installer (#991)

* feat: Implement SKIP_SHORTCUT for installer

* feat: Update Linux install script to use NSIS-based installer instead

* feat: Wine detection for installer shortcut suppression

* fix: Revert WINEPREFIX back to XDG Home

Oops.

* fix(linux): Forgot to use the variable here

* fix(linux): Don't error if INSTALL_LOCATION exists but is empty

* fix(linux): "Program Files" has a space
