[cli] update `br scan` to allow network interface selection for mDNS binding #260

Within the OTBR practice application, the BR host will have several interfaces. When users want to discover the border router using mDNS, they will need to choose the specific interface.

This change introduces a new option for the CLI command br scan. User can now specify a network interface using the syntax `br scan --netif . The chosen interface will be used for mDNS binding through socket options.
