build: Build binaries for Linux AArch64

[kjarosh]

GitHub added new runners with ARM processors, and we are able to easily build binaries for AArch64 that way!

Let's see how well this works!

I made a pull request for this fork at https://github.com/kjarosh/ruffle/pull/8
I don't know what values you are expecting for max_outliers, so I separated that when matrix.os is ubuntu-24.04-arm and added a separate max_outliers_arm value at few toml files.

added a separate max_outliers_arm value at few toml files.

I don't think this is a good idea... 😶
It's not like the ARM runners are less accurate compared to Flash Player, because they are ARM... They are just inaccurate in a different way than x86, and the current expected outputs match that more.

The arm desktop builds are somehow workable at my games. Last arm build that was working was with the last commit from October. In November there is a commit that is causing this:
thread 'main' panicked at desktop/src/app.rs:466:14: GUI controller should be created: Limit 'max_color_attachments' value 8 is better than allowed 4
Same through Jan 17(this fork time).
Build logs are at my colin-i/ruffle actions.
I will resolve that at a future time if no one will do that.

This pull is solving the error but at the moment must be moved to same wgpu as the master: 23. #6994
