Add hint for potential increase of CONFIG_BT_NIMBLE_HOST_TASK_STACK_SIZE

[juliankrieger]

In my recent work, I've come up with in issue that resulted in a stack overflow in nimble_host, when calculating expensive data inside an on_read callback. I could resolve my issue with the configuration option above.

Another idea would be to run a smaller tokio/mio thread and signal it to do the expensive calculation.
