patch 9.0.1871: Github CI does not run i386 job

Problem:  Github CI does not run i386 job
Solution: Add a i386 architecture

Add CI testing for i386

message_test recently failed on i386, which exposed a gap in the CI
testing.  Convert the shadowdir job to one that runs on i386 so we get
32-bit test coverage.

Since the GHA runners are x86_64, we can enable the i386 architecture
in dpkg and install i386 packages for the i386 CI jobs.  However, this
can't currently be done with features=huge since that would require
installing python3-dev:i386, which breaks the CI environment.

closes: #12975
