Add rustflags to desc and help output

`gn desc` doesn't list a target's / config's rustflags, even though
TargetDescBuilder already has support for it.

This CL adds rustflags support to ConfigDescBuilder as well, and makes
the desc command print them. While we're already at it, it also adds it
to the help command's output.
