[Flight] Allow overriding request.timeOrigin

[lubieowoce]

Manually stacked on #35506

Currently, IO that finished before the request started is not considered IO:

react/packages/react-server/src/ReactFlightServer.js

Lines 5338 to 5343 in 6a0ab4d

	const ioInfo = info.awaited;
	if (ioInfo.end <= request.timeOrigin) {
	// This was already resolved when we started this render. It must have been some
	// externally cached data. We exclude that information but we keep components and
	// awaits that happened inside this render but might have been deduped within the
	// render.

This leads to loss of debug info when a flight stream is deserialized and serialized again.
We can solve this by allowing "when the the request started" to be set to a point in the past, when the original stream started by doing

const startTime = performance.now() + performance.timeOrigin
// ... stuff happens and time passes...
ReactServer.renderToReadableStream(..., { startTime })
