winegstreamer: Allocate source media buffers in the PE components.

This necessitates an extra blit for the input data, but this is necessary for both WoW64 support and an internal rework of the source path in wg_parser to use GstAppSrc. Since source data is usually compressed and not a bottleneck, we don't expect this to affect performance.
