Debugger: Cleanups, no functional change.

- Add virtual hook to TeamMemory for retrieving area information
  from the target team.
- Implement said hook in DebuggerInterface.
- Adjust RetrieveMemoryBlockJob to use said hook to retrieve the
  writable state of the target block rather than calling
  get_memory_properties() directly.
