Add a built-in userdiff driver for the Swift programming language so that
diff hunk headers and word diffs work out of the box for ".swift" files.

I noticed other languages add a test_language_driver entry to
t/t4034-diff-words.sh with corresponding pre/post/expect
fixtures. Should we add something similar for Swift?

In the past, these test scripts turned out to
be non-trivial to get correct and it was a burden for both the author
and the reviewers. It would certainly exceed the scope of a microproject.

Got it, thanks for the context.

FWIW, I tested the changes against a recent WWDC 2026 sample
project[1] I was playing around with, and the new user driver appears
to work well.
