Move layoutlib typeface implementation to delegate.
Also move BridgeContentProvider to its own class to make it
less messy in BridgeContentResolver.

+ * Delegate implementing the native methods of android.graphics.Typeface
+ *
+ * Through the layoutlib_create tool, the original native methods of Typeface have been replaced
+ * by calls to methods of the same name in this delegate class.
+ *
+ * This class behaves like the original native implementation, but in Java, keeping previously
+ * native data into its own objects and mapping them to int that are sent back and forth between
+ * it and the original Matrix class.
