dnsmasq: introduce config support for forced DHCP options
Introduce a new UCI list setting `list dhcp_option_force` which is available in sections of type `dnsmasq` and `dhcp`. The `dhcp_option_force` setting has the same semantics as `dhcp_option` but generates `dhcp-option-force` directives instead of `dhcp-option` ones in emitted native configuration.
