pw_stream: Allow staging data to MemoryWriter end

Changes the memory writer to use std::memmove to allow data to be staged
to the unused portion of a MemoryWriter's buffer before it is written.
This is useful for operations that require direct access to a buffer to
build data before it is flushed to a MemoryWriter.
