Fix the Java Bridge to support coercing to Java arrays

This change adds support for coercing to Java arrays when passing JavaScript
objects to the methods of Java objects injected using the Java Bridge.
- Modify JavaType to store the type of the array elements when the type of the
  value is TypeArray.
- Add logic to create Java arrays and to interrogate JavaScript objects for
  their length property and array elements.
- Modify existing CoerceJavaScriptXXXToJavaValue() methods to take an
  additional coerce_to_string argument. This is required because we require
  slightly different behaviour when coercing to Java strings, depending on
  whether or not the value is an array element.
- Modify JavaBridgeChannel to override
  NPChannelBase::OnControlMessageReceived() to avoid DCHECK().

Also fix a potential overflow when converting JavaScript numbers to Java
strings.
