Bluetooth: host: Public access to bt_addr_le_is_resolved()

[koffes]

Summary

Currently, bt_addr_le_is_resolved() resides:

zephyr/subsys/bluetooth/host/addr_internal.h

Line 14 in c4ddc85

bool bt_addr_le_is_resolved(const bt_addr_le_t *addr);

It would be great to have access to this function through a public API.

Ref discussion with @Thalley .

Describe the solution you'd like

The declaration of bt_addr_le_is_resolved() should be in a public header.

I strongly suspect this function does not do what you think it does :)

Please explain what the function you want should do so we are all on the same page and can discuss adding it.

Was about to add something similar here:
One issue with this, is that the addr->type exposed to the application layer, are usually (always?) either BT_ADDR_LE_PUBLIC or BT_ADDR_LE_RANDOM, so using this on a public facing bt_addr_le_t may always be false.

[Thalley]

bt_addr_le_is_identity may be a better solution (already public as well)

#95011: I'm adding documentation to bt_addr_le_is_resolved() to explain what it does.
