build: Store depends in GeneratedList instead of Generator

Since they are actually dependencies out the output not the Generator
itself.

This fixes dependency issues in the ninja backend, allowing Meson to
rebuild more accurately. It also does sometimes in the vs backend, but
there are problems in the vs backend I'm not sure how to solve. The
vsbackend is, itself, so fragile looking I don't want to get too
involved with it.
