* Revert "Revert "XdsClient: add unit test and fix watcher notification bugs (#30823)" (#30942)"
This reverts commit 6d2c4a8314.
* use GRPC_CUSTOM_JSONUTIL macro for JsonPrintOptions
This adds a unit test for XdsClient and fixes several watcher-notification bugs found in the process. Specifically:
- When an ADS stream fails or an xDS channel reports a connectivity failure, report an error only to the watchers for resources being subscribed to on that particular channel, not to watchers on other channels.
- Cache the error status for the channel, so that if a new watcher is started after the channel reports the error, we can immediately report that error to the new watcher.
- If a resource is NACKed and has not been previously cached, or does not exist, report that fact to any new watcher that may be started later.
- If a resource in an ADS response is unparseable but is wrapped in a `Resource` wrapper, we do know its name, so record the validation failure in the cache and report it to the watchers.

Previously this failed 1/1000 times with a 1s timeout, giving a
`Deadline Exceeded` error. I was able to reproduce the failure in
22/1000 times with a 500ms timeout. Changing it to a 2s timeout in this
PR, the failure did not reproduce in 5000 runs.
