Bluetooth: Host: Add generic pairing query callback

Similar to pairing_confirm this callback is called each
time a peer requests pairing, but for all types of
pairings, except SSP. The pairing req/rsp information is
passed as a parameter so the application can decide
wheter to accept or reject the pairing.

Fixes: #21036
