Support aarch64 architecture

[binaryfields]

Are there any blockers to enable support for arm64 architecture?

Asahi Linux is close to releasing alpha image/installer that runs on M1 Macs. It would be great to have Blender available on that platform.

As far as I know, the arm64 build of Blender is for macOS on Apple Silicon, Blender does not have arm64 build for Linux, so I think no one want to package what the upstream won't.

Yet the flathub.json was recently removed, generating broken aarch64 builds.

I would also really like for an ARM64 flatpak for blender
there are many old versions for arm64 in the likes of ubuntu and debian repos but those don't stay up to date like the flatpak

I used to build Blender from source, which would have made an ARM64 build trivial, but as it was way too much work for anybody to follow, we changed it to use a prebuilt binary from blender.org

Please first ask Blender upstream to build something for ARM64 and we would most likely add an ARM64 Flatpak as well I guess, but in the meantime there's not much we can do. 🤷

#119 build from source, but I asked people that use Blander more than me (given that I actually don't) if it could be tested making sure nothing was forgotten.
