Swift/Ninja: Add description to Swift object build steps
By default, Ninja displays the full build command for the object which
is very verbose. Warnings are often lost in the noise, and compile
errors take some searching to find. If a build step fails, Ninja will
still print out the full build command, so there's no loss of useful
information.
Fixes: #25853
