No `swiftSettings:` for `.plugin` targets?

Description

There's apparently no way to specify, e.g. -warnings-as-errors for a .plugin target. Seems like an obvious oversight.

Yes, that is correct. Not sure if it was an oversight, it matches the proposal.

[dabrahams]

It can be kludged around by putting all the functionality in a library, so there's no good reason to disallow the settings directly in the plugin.

@abertelrud do you remember the reasoning for not exposing it?
