Ben Wagner 1ca50524c4 Allow better font fallback. 
The intent is to allow the creation of a MakeFontMgrRunIterator which
uses the passed font's typeface as the primary typeface, but uses a
given family name and style as for the request for fallback fonts. This
allows the user to provide the actual request for the primary typeface
as opposed to making a request based on the resolved primary typeface
(which may not be the right thing to do).

To support this, the selection of language for fallback is also added.
Since this information is already in the language iterator, this change
makes the font iterator the lowest priority iterator for consume,
allowing the font iterator to rely on the current value of the language
iterator to provide the language.

In order to allow these changes to be exercised, this also adds a few
generic 'Make' methods for bidi and script. These new methods will use
the best available implementation. These are needed since the most
capable implementations may not always be available (such as on our
testing ios builds).
