DelayedDelivery Poller doesn't handle messages going over the size limit gracefully

[danielmarbach]

Describe the suggested improvement

Is your improvement related to a problem? Please describe.

For messages close to the maximum size it is possible that the delayed message poller cannot send a message to the destination queue. When that happens it tries to add a failed Q header which makes the attempt also fail.

Messages cannot be larger than 65536 bytes.
Failed at dispatching the delayed message with PartitionKey:'2023030208' RowKey: '20230302082154_5989ca79686f48c593f8bf34a7ec4126' message ID: '094bc4f2-152e-4e0c-a983-afb9006dd811'

the poller doesn't handle such a situation gracefully nor does it trigger critical error actions. For example the recoverability code would trigger the critical error in such a situation.
