Allow `targetName` for `object package`

Compiler version

3.7.3

Minimized code

➜  cat something-else.scala

import annotation.*

package p:
  package q:
    @targetName("mypq")
    object `package`:
      private[p] def f = 42

Output

➜  scala-cli compile --server=false -S 3.7.3 something-else.scala

Expectation

Since the file name, and therefore the package object name, is arbitrary and may require special encoding, I would like to "fix" the name to something benign (instead of something-else).

Packages don't take annotations, but object syntax does, and possibly package object syntax could be made to.

It would be nice if targetName were permitted for package objects.
