Add new network capabilities to support automotive head unit via USB

Browse Source 
- Add a new transport type for USB and a new network capability
to support automotive head unit.
- In order to pass DnsManagerTest#testTransportTypesEqual, Android.bp
needs to link to dnsresolver_aidl_interface-V8-java. That test checks
whether the TRANSPORT types defined in NetworkCapabilities are the
same as IDnsResolver.aidl.

Test: atest FrameworksNetTests
