Record Scala package object as provided name (#15582)

The package object should also be recorded as provided name, as it also behaves as an object. 

An example that will fail without this fix:

File t.scala:
```
package object example {
   trait T[A]
}
```

File a.scala:
```
package example

package object a {
   implicit val tString: T[String] = new T[String] {}
}
```

File b.scala:
```
package example.b

import example.T
import example.a._

object B {
   val x = implicitly[T[String]]
}
```
