ci: Add arch-matrix build QA workflow (just 32-bit and 64-bit x86 arc…

…hitectures for now)

This is added to catch any 32-bit-related issues. We (upstream) are generally not
using 32-bit architectures anymore, but downstream packagers still package software
for 32-bit platforms. Let's not make their job more difficult than it already is.
