gfe-relnote: Construct QuicMemSliceSpans from a QuicMemSlices without copies.
QuartcSession uses this functionality to send queued message frames without
copying the data backed by QuicMemSlices in its queue.
Note that this extends the platform/api by adding a new constructor to
QuicMemSliceSpan. It adds a corresponding constructor to QuicMemSliceSpanImpl,
so this will need to be merged into chromium manually. The changes required
should be minimal (<10 lines of code).
Not flag-protected, since the only changes are (a) platform/ code that is not
called anywhere except quartc/ and (b) quartc/ code that is not called in GFE.
