Some work towards getting stack traces:

* Added a virtual Architecture::CreateStackTrace() and added a basic
  implementation in ArchitectureX86. Fleshed out StackTrace/StackFrame a bit
  and added StackFrameX86. This needs to be organized differently, though, so
  that we can get the maximum available information for each stack frame,
  depending on what info is available for the respective function.
* Added job to get the stack trace for a thread.
* Added stack trace related handling in TeamDebugger. Reorganized the thread
  state/CPU state/stack trace change handling a bit -- we're using a
  Team::Listener now, and do things asynchronously.
* Added a StackTraceView to display the stack trace of the current thread. No
  function name available yet, otherwise working fine.
