Description

Currently, arm64 builds of debian/ubuntu images take ~3-4 hours to build. We can reduce the time by cross compiling the arm64 images and leveraging BUILDPLATFORM and TARGETPLATFORM docker variables.

There were previous attempts to do this in the following PRs:

• Working Docker cross-compiling for Fedora 39 Sunshine#2059
• Cross compiling Sunshine#2018
• build: cross compile linux Sunshine#2020
• build(docker): use cross compilation Sunshine#3635

Those PRs all went stale, or had too many conflicts.

Since those attempts, we now only need to worry about debian and ubuntu images, instead of Fedora images which are no longer used in Sunshine.

As an alternative, we can compile Sunshine outside of docker, then copy the binary into the images. This is probably more feasible and faster.
