access-list 105 deny ip any any
Does anyone know if this ACL applied to an interface will block incoming ARP messages?

no it won't. ARP is not IP packet

It can be useful to block arp requests using mac address acls and tying them to the vlan interface.
All ARP frames use 0x806 Ethernet protocol type.
