[PyQt] Include software rendering and HLSL compiler in the PyQt5 wheels for Windows

[Cody Scott]

Sorry when I said msvc directory I meant the Qt bin directory, for example

C:\Qt\5.10.1\msvc2015\bin

I meant to ask if the libEGL.dll and libGLESv2.dll files come from the
C:\Qt\5.10.1\msvc2015\bin directory or another one?
