Anders Fugmann c5e1f38583 Kotlin extractor: restore external file-class locations under K2
Why this is needed:
- Under K2, top-level declarations from external binaries are attached directly
  to IrExternalPackageFragment rather than to an IrClass file-class parent.
- That bypassed the normal class-source location path, so some external file-class
  entities ended up without stable binary file locations.
- Missing/unstable locations caused drift in tests that depend on external file
  class member resolution and location facts.

What this changes:
- Resolve binary paths from IrMemberWithContainerSource (JvmPackagePartSource)
  via a dedicated getContainerSourceBinaryPath helper.
- In KotlinUsesExtractor, when extracting top-level external declarations,
  attach file-class location from container-source binary path when available.
- Track external file classes whose locations were emitted to avoid duplicate
  hasLocation facts.

This targets the K2 external file-class location gap (for example file_classes and
external-property-overloads parity).
