Display offsets for dex frames.

When adding a dex frame, no offset is ever printed even if the dex data
is coming from a non-zero offset map. Fixed so an offset is printed
in this case.

Previous the line looked like this:

  #17 pc 0000000000500d7a  /product/app/GoogleCamera/GoogleCamera.apk (com.google.android.libraries.camera.async.AndroidPriorityThread.run+10)

Now looks like:

  #17 pc 0000000000500d7a  /product/app/GoogleCamera/GoogleCamera.apk (offset 0x11d0000) (com.google.android.libraries.camera.async.AndroidPriorityThread.run+10)

Add new unit test for this case.

Bug: 134420076

Test: Wrote new unit test, and verified a non-zero offset for dex file
Test: data results in a frame with a non-zero offset.
