Adds a cross file, changes how 64 bit is detected by meson and adds arm64ec builds to some of the CI jobs.

The build-test-package-linux.yml can be modified to work with this, but it needs the toolchain from either the AUR or somewhere else so i dropped it.

build-llvm.yml does not work. xwin does not have arm64ec support so it fails to link:
lld-link: could not open 'softintrin.lib'

I want to try to get dxvk-nvapi into Proton arm64ec, to do that i need to get it into dxvk-nvapi here. That's the justification behind this change.

I built and tested this locally with Proton Experimental on a Retroid Pocket 6. It looks to be working as expected

Thanks for this, Looks reasonable at a glance, but I have a few questions and/or suggestions.

I just added it everywhere i could now, please let me know if there's something here that you dont like/that i should revert again.

build-proton now builds on 1 runner as x86_64 with the cross toolchain.
build-test-package-linux also has the toolchain and builds arm64x so that we get them in artifacts. I'm testing the builds on my master branch and will make sure the artifact works.
package-release.sh now has a --build-arm64x flag that im using for these 2 workflows

One note here is that I'm not testing with an NVIDIA GPU and I dont have a good enough overview of nvapi to test everything

👍

One more minor request from me would be mentioning --build-arm64x as a valid optional flag for package-release.sh in our README. Other than that, I'll defer final judgement to Jens.

Kind of annoying that we need to fetch the toolchain directly from github, but seems that this is unfortunately the way to go. See some very minor nits/suggestions, otherwise looks good and fine to get this in.

For the long term we could tweak the readme to mention arm64x there as well, but that is for another day. Same for exploring if we can go all the way meson (instead of msbuild directly) for msvc builds.

Looks good. Thanks! Do you mind squashing some commits before we merge this?

yeah sure i can move some stuff around here

I think this should be pretty good, i created a backup branch just in case
