[dualtor][minigraph.py] Add soc_ipv4 and cable_type to MUX_CABLE (#10776)

Browse Source 
Why I did it
To further add cable_type and soc_ipv4 field to table MUX_CABLE, this PR tries to parse the minigraph like the following:
```
      <Device i:type="SmartCable">
        <ElementType>SmartCable</ElementType>
        <SubType>active-active</SubType>
        <Address xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>192.168.0.3/21</d5p1:IPPrefix>
        </Address>
        <AddressV6 xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>::/0</d5p1:IPPrefix>
        </AddressV6>
        <ManagementAddress xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>0.0.0.0/0</d5p1:IPPrefix>
        </ManagementAddress>
        <ManagementAddressV6 xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>::/0</d5p1:IPPrefix>
        </ManagementAddressV6>
        <SerialNumber i:nil="true" />
        <Hostname>svcstr-7050-acs-1-Servers0-SC</Hostname>
      </Device>
      <Device i:type="Server">
        <ElementType>Server</ElementType>
        <Address xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>192.168.0.2/21</d5p1:IPPrefix>
        </Address> 
        <AddressV6 xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>fc02:1000::2/64</d5p1:IPPrefix>
        </AddressV6>
        <ManagementAddress xmlns:d5p1="Microsoft.Search.Autopilot.NetMux">
          <d5p1:IPPrefix>0.0.0.0/0</d5p1:IPPrefix>
        </ManagementAddress>
        <Hostname>Servers0</Hostname>
      </Device>
```

How I did it
get_mux_cable_entries will try to get the mux cable device from the devices list and get the cable type and soc ip address from the device definition.

How to verify it
Pass the unit-test
