Refactor FormData and FormDataList for better integration with Blob and FileWriter's BlobBuilder.

With BlobBuilder [1] one can construct a Blob by combining arbitrary Strings and Blobs, and then send the synthesized Blob via xhr.  This is very similar to what current FormData [2] is doing, and to send such synthesized Blobs we'll need to utilize the same code as FormData.

To avoid duplicated code and clean up internal structures, it'd be better to have a common internal implementation for FormData, Blob and BlobBuilder.
