Add wire_format_lite_inl.h include to implicit_weak_message.cc

implicit_weak_message.cc is part of protobuf_lite.dll, and it includes
wire_format_lite.h, which includes the dllexport inline function
WireFormatLite::WriteGroupToArray which will therefore be emitted.

WriteGroupToArray in turn calls the inline function
InternalWriteGroupToArray, however that definition is provided in the
_inl file. To make sure the definition is available, the _inl file must
be included.

Before Clang r344987 the build worked anyway (due to luck), because
InternalWriteGroupToArray was emitted into other object files (e.g. in
wire_format_lite.obj). After that Clang revision, those definitions
started getting inlined, and so are longer available and cause a link
failure for the reference from implicit_weak_message.obj.
