The flag is hardcoded for now, it'll be a MiniInstaller flag later

Headless mode apparently worked some time 6 years ago, however has been basically unusable in the past few years.
This PR revives that idea by adding a
Headlessdriver to FNA3D and patching FNA, to completly bypass any window creation / GPU APIs and therefore allow Celeste to be run on servers without a GPU, such as GitHub Actions.It is applied by specifiying the
headlessflag to MiniInstaller. It's no longer a runtime flag, since a) you're never switching between them and b) we need to apply MMR patches to FNA.Currently it doesn't apply any optimizations and only provides updated FNA3D libraries for Linux, which is why this is a draft.
Note that this PR is based of #843, due to MiniInstaller changes
