Flatpak arm64 support (#8033)

* Add qemu for arm builds on flatpak

* Increase timeout-minutes

Mainly meant to retrigger GitHub actions (free GitHub actions runners have a max runtime of 6 hours)

* Change arm64 flatpak to build barebones, rather than through emulation

This new addition is highlighted in GitHub's new blog post: 
https://github.blog/changelog/2025-01-16-linux-arm64-hosted-runners-now-available-for-free-in-public-repositories-public-preview/

* Rename from arm64 to aarch64

* Potental fix for gst-plugins-good compilation

* Initial appimage arm64 builds

* Add inputs.arch variable

* Temporarily completely isolate arm64 and x86 dependencies

* Fix mesa download link and remove temp comments

* Disable libunwind in gst-plugins-good

* Revert changes in build_check_cache.yml

* Disable nls & static options in gst-plugins-good

* Rebase on main

* Re-add flatpak arm build

* Update gst-plugins-good to 1.24.10

This should be the version that received complete arm64 support

* Trying a solution

* Revert "Update gst-plugins-good to 1.24.10"

This reverts commit b416dcd0ae8a908811925ae65f7d49c290e3a194.

* Remove previous build-options

* Try installing the proper arch version of Meson

When building on a local arm64 device it runs properly.

* Remove sudo commands

* Use dnf rather than apt-get

* Try installing meson before the flatpak builder

* Change flatpak runner

This uses a more experimental version of the flatpak runner provided by Flathub

* Temporarily enable artifact upload

* Resolve merge conflicts

* Add arch variable into flatpak name

* Revert to using Gnome 46, rather than Gnome 47

* Add curl dependency

* Revert "Add curl dependency"

This reverts commit 888a0c4a758af58c410a0b45ecca7eb56e359d37.

* Clean up

* Define ubuntu version

Seems to be needed due to the arm version still being in public beta
