ci: Add ubuntu-24.04-arm regular CI and release artifact

[ADKaster]

Fixes #2533

the arm64 artifact will be called wabt-$VERSION-ubuntu-24.04-arm.tar.gz without any changes to the release-archive action.

Oh that's fun. Looks like there's a gcc-13 ICE in the arm64 build.

That something y'all want to report or should I spin up an arm64 box to do it myself?
