[CMake] Extend copy-legacy-layouts dependency to swiftmodules

... and other products as well.

Before this change, the dependency was enforced only for stdlib object
files -- since according to the Ninja dependency graph other libraries
can be scheduled as soon as the swiftmodules are ready, there is a
chance that we attempt to build those before legacy layours are copied.
