Some improvements to process state dumpsys output.

The detailed dumpsys output of ProcessRecord had some formatting
issues.  Cleaned this up, also reorganized and improved some of
the other output.

And improved debugging output of capabilities -- have special
formatting to print the flags in a more human-readable way, and
added this to the process list summaries.

Looks like this:
