Remove user specified typeface id.

Now that there may be multiple font managers in a process the typeface
ids must be unique across all typefaces, not just unique within a font
manager. If two typefaces have the same id there will be issues in the
glyph cache. All existing font managers were already doing this by
calling SkFontCache::NewFontID, so centralize this in SkTypeface.
