Move build badge examples into services/ (#2234)

all-badge-examples is a common cause of merge conflicts. It’s difficult to adjust the badge categorization in that file – or to understand the diff – because it requires moving a block from one point to another. It’s much easier to edit a badge’s category in one place.

This starts the process of breaking up what’s left of that file, following up on the work from #1931. New-style services can only be in one category, which means legacy service examples have to be split along category lines. I split out separate legacy service classes where I could do so easily, leaving behind the ones which require more work, for one reason or another.
