Bug 1345294 introduced nsPrefBranch::{get,set}StringPref(), which allowed the
getting of utf8 strings from prefs, which previously required using
nsISupportsString with {get,set}ComplexValue. That bug also converted most
uses.
This patch finishes the job.
- It removes the nsISupportsString support.
- It converts existing code that relied on the nsISupportsString.
- It removes the lint that was set up to detect such uses of nsISupportsString.

This makes the code nicer. In particular, it removes many getter_Copies()
calls. The patch also converts a lot of nsCStrings to nsAutoCString, which will
avoid heap allocation in the common case.
The patch also renames PREF_CopyCharPref() as PREF_GetCStringPref(), because
it's actually getting a string, not a char, and that matches the existing
GetCString() and GetDefaultCString() methods. Correspondingly, it also renames
PREF_SetCharPref() as PREF_SetCStringPref().
The |aPrefName| arguments in nsIPrefBranch.idl remain as |string| because they
almost always involve passing in C string literals, and passing "foo" is much
nicer than passing NS_LITERAL_CSTRING("foo").
It's worth noting that early versions of this patch used |AUTF8String| instead
of |ACString|. But it turns out that libpref stores prefs internally as Latin1.
And |ACString| is compatible with Latin1 but |AUTF8String| isn't, because
non-ASCII Latin1 strings are not valid UTF-8!
