This change does the following:

- Allow disambiguation of which APK(s) should be used for decoding by
  adding an APK directory override argument to stack.py. The alternate
  directory is also handy if using bundles, where the APK files need to
  be generated from an .aab file.

- Augment Clank binary wrapper scripts with a "stack" command,
  effectively acting as a stack.py wrapper that points stack decoding at
  only the relevant APK files (as opposed to a typical stack.py
  invocation, forced to look at out/../apks/, which may contain many
  APKs).

- For lines in the trace that already have symbols, but cannot be
  decoded by the script (ie. lines from on-device Android runtime
  libraries), don't print <UNKNOWN> - fall back to the symbol given in
  logcat instead.
