Provide d3dcompiler_47 DLL in the Windows Phone 8.0 packages

The 32-bit d3dcompiler should be shipped with WP8.0 packages, as it is possible for it to not to be found in the PATH, resulting in the description below.

Currently I am unable to deploy Qt Quick apps to both device and phone. Phone runs Quick Forecast demo app fine.

qtd3dservice fails to upload the shaders to Emulator and WP8.0 device:

1) With connected phone, emulator off:
D:\Qt\5.3\winphone_arm\bin>qtd3dservice.exe --verbose 2
qt.d3dservice: A Windows Phone has connected.
qt.d3dservice: Unable to open registry key for Appx discovery: "No such file or directory"
qt.d3dservice: "Schnittstelle nicht unterst³tzt"
qt.d3dservice: Found app "

{BDDCF029-F4D2-4107-8D82-F65B89551751}

" on device "0".

{BDDC...}

is the Quick Forecast demo app on the phone.

2) With emulator, phone disconnected
D:\Qt\5.3\winphone_arm\bin>qtd3dservice.exe --verbose 2
qt.d3dservice: An emulator was activated: 1
qt.d3dservice: Unable to open registry key for Appx discovery: "No such file or directory"

"Schnittstelle nicht unterst³tzt" is German, English text reads "No such interface supported", see https://lh5.googleusercontent.com/-GjFr23_R8oo/U3rWKE8_rFI/AAAAAAAAAHI/AcXHZ6Kkarw/w440-h330-p/Untitled.png (reported by another user in comments on Qt Weekly #11)

Looking into C:\Users\Peter\AppData\Local\qtd3dservice\0{2AB578BF-CBD6-47DF-BFB8-79C655493052}

• binary folder is empty
• source folder countains 4 shader files

Environment:
Windows 8 Pro (not 8.1), German language
Qt 5.3 binary via netinstaller
MSVC 2012 Pro
Windows Phone SDK 8.0 - DEU (= German)
Nokia Lumia 520 8.0 (latest official update)

I don't know if "No such interface supported" is the reason for the "Unable to upload binary" issue. Looking at d3dservice.cpp I don't understand where this error comes from.

I am willing to give more information on request.
