Provision WSL and the test containers after the build instead of alongside it (#5873)

Windows jobs have died with "The hosted runner lost communication with
the server" while the build and the 8 GB WSL2 VM were competing for the
runner's 16 GB. The WSL, SQL Server, PostgreSQL, RabbitMQ and IBM MQ setup
steps now wait for the build like the Azure steps already did.
