1. If the write Subscriber cancels with the item cached, release it.
2. If the write Publisher emits an error while the item is cached, when
the write Subscriber subscribes, release the cached item and emit the
error signal.

This commit improves CORS support by:
- Using CORS processing only for CORS-enabled endpoints
- Skipping CORS processing for same-origin requests
- Adding Vary headers for non-CORS requests
It introduces an AbstractHandlerMapping#hasCorsConfigurationSource
method in order to be able to check CORS endpoints efficiently.
Closes gh-22273
Closes gh-22496
As of Coroutines 1.2.0-alpha, Dispatchers.Unconfined
is a stable API so we can leverage it in order to get
better performances in our Reactive to Coroutines
bridge.
See gh-19975
The cancellation callback in asynchronousReadFileChannel must be called
before the first read I/O or otherwise if cancellation signals happens
immediately the onDispose callback may be missed.
The DefaultBufferFactory workaround however remains in place until an
expected additional fix arrives with Reactor Core 3.2.9.
See gh-22107
Update `AnnotationUtils` so that `RepeatableContainers.none()` is used
when performing an exhaustive search for merged annotations. These
parameters were accidentally removed in commit 210b1789 and weren't
caught earlier because we were missing a test.
Closes gh-22702
Update `addConventionAnnotationValues` so that `value` attributes
do not override existing annotation values. The aligns the new
`MergedAnnotations` API with the previous `AnnotatedElementUtils`
logic.
Closes gh-22703
