Remove stack trace from Binder#getCallingUidOrWtf

Rather than Log.wtfStack, use Slog.wtf if Binder#getCallingUidOrThrow
would throw. Accept an argument for the caller to provide a message in
the resulting log, if generated.

This has the following advantages over the previous design:
1. Collecting a stack is expensive, so it wouldn't be possible to use
   the previous design in hot codepaths.
2. Using Slog instead of Log.wtf means neither app processes nor
   system_server would crash. We don't necessarily need to crash app
   processes as this method is for information gathering purposes only.
3. Accepting a message as a parameter allows immediate callers to
   identify themselves without needing a stack trace.

We plan to use this method in code generated by the AIDL compiler for
system services. This will inform the decision making process w.r.t. the
migration to getCallingUidOrThrow.
