Allowed translator_hlsl and glsl to be built as shared libs on windows.

The problem was gyp was out-of-date (I rolled it to 1080) and ShaderLang.cpp exports were not being exported because it was in translator_common which is a static lib.

I tested shared library and static library builds in debug and release and also the checked in ANGLE.sln build.
