Add desktop binary export support to the examples

win-x86, win-x64, linux-x64 and mac-universal targets, validated on
the pong pipeline: Makefile binaries/ci-binaries targets, desktop
export presets, ci-binaries step in the Woodpecker example. Mac is a
single universal (intel + arm) build with built-in ad-hoc codesign and
needs ETC2 ASTC texture import enabled in project.godot.
