[Windows] Add binary data transfer from .net extensions.

zcr01 · zcr01 · commit 697b2af4acbc · 2016-12-13T17:12:20.000-05:00
Exposes PostBinaryMessageToJS(byte[] data, ulong size) to the .net extension bridge.
 - Uses XW_MessagingInterface2 to return an ArrayBuffer to the Javascript client
 - Improves data transfer speed for large amounts of raw data, as translating from a string is slow in Javascript.
