Unresolvable diagnostics for access control on import specifiers

[compnerd]

Description

It is impossible to reconcile the diagnostics emitted for access control on imports.

Reproduction

package import typealias SWLLBuild.llbuild_pid_t
public import typealias SWLLBuild.ProcessDelegate
@_exported public import struct SWBLLBuild.CommandExtendedResult

package class TaskProcessDelegate: ProcessDelegate {
  package func processStarted(pid: llbuild_pid_t?) {
  }
}

Expected behavior

You should be able to specify the minimally visible specifier for the types.

1. Module 'SWBLLBuild' is imported as 'public' from the same file; this 'package' access level will be ignored
2. Public import of 'SWBLLBuild' was not used in public declarations or inlinable code

Environment

Swift version 6.2-dev (LLVM 6447c07cd7bd63f, Swift d9e07280e43d548)
Target: x86_64-unknown-windows-msvc
