[arabic] Implement Windows-1256 private shaping
Bug 1045139 - The Arabic text with "MS Sans Serif" font is rendered bad https://bugzilla.mozilla.org/show_bug.cgi?id=1045139 This is only enabled on Windows platforms, and requires support from Uniscribe to work. But for clients that do hook up to Uniscribe, this fixes shaping of Windows-1256-encoded bitmap fonts like "MS Sans Serif". The code and table together have just less than a 1kb footprint when enabled. UNTESTED. I might even have broken regular Arabic fallback shaping.
