Issue Description:

Description

Currently the binary target feature in the Swift Package Manager only works for single binary dependencies. The API for `Target` is shaped so that its own static method for returning a `.binaryTarget` does not take a `dependencies` array like the standard `.target` method.

Setting the `dependencies` property on a `Target` type when that type is `binary` results in a crash to the SPM.

There is a workaround for the including dependencies in binary targets but it includes adding a dummy target to your `package.swift` and the result also generates warnings in an integrator's xcode project.

The desired change to the SPM is to allow `binaryTarget`s to declare `dependencies` in their `package.swift` files.

This thread has good detail on the issue and the known workaround for it: https://forums.swift.org/t/swiftpm-binary-target-with-sub-dependencies/40197/11

Interested to see this implemented. The errors when a binary dependency is missing are very confusing. Wondering where to file an issue for better error messages.

I'm actually running into this issue now, and it's fairly painful. Would really love to see a way to handle this better.
