We now moved OEM font customization outside of system image and all
system font modifications are in /product directory.
In this CL, only customizationType="new-named-family" is supported.
My previous CL If58711fc038898175fcad0ae095865312bd738e2 breaks test
cases in CtsGraphicsTestCases but TreeHugger didn't catch my mistake
becasue the test cases are not annotated as Presubmit.

ASystemFont API provides an ability of enumerating the system available
font files with some additional information.
ASystemFont reads /system/etc/fonts.xml and give the information to
developers.
Lots of developers reads fonts.xml by themselves but that is not a part
of public API and the structure is subject to change. This API is a
replacement of the reading fonts.xml by developers.
