feat: support for loong64 linux

[wszqkzqk]

LoongArch is a new RISC ISA developed by loongson. There are already a lot of community support and testing about it.

I've added support of loong64 upstream in conda/rattler#1534 so we may take it forward now.

Updated the branch, as we now have a new version of rattler that supports this.

Updated the branch, as we now have a new version of rattler that supports this.

It has been successfully built on Arch Linux for Loong64 now with this PR applied and the trampoline binary manually downloaded.

So what should we do? Add the trampoline binary manually?

[wszqkzqk]

Does the trampoline binary file need to be updated by the bot?

[baszalmstra]

@nichmor did you do this manually last time?
