[Fizz] Client render the nearest child or parent suspense boundary if…

… replay errors or is aborted (#27386)

Based on #27385.

When we error or abort during replay, that doesn't actually error the
component that errored because that has already rendered. The error only
affects any child that is not yet completed. Therefore the error kind of
gets thrown at the resumable point.

The resumable point might be a hole in the replay path, in which case
throwing there errors the parent boundary just the same as if the replay
component errored. If the hole is inside a deeper Suspense boundary
though, then it's that Suspense boundary that gets client rendered. I.e.
the child boundary. We can still finish any siblings.

In the shell all resumable points are inside a boundary since we must
have finished the shell. Therefore if you error in the root, we just
simply just turn all incomplete boundaries into client renders.
