[Fizz][Float] Do not write after closing the stream (#27541)

Float methods can hang on to a reference to a Request after the request
is closed due to AsyncLocalStorage. If a Float method is called at this
point we do not want to attempt to flush anything. This change updates
the closing logic to also call `stopFlowing` which will ensure that any
checks against the destination properly reflect that we cannot do any
writes. In addition it updates the enqueueFlush logic to existence check
the destination inside the work function since it can change across the
work scheduling gap if it is async.
