ANDROID: GKI: Add hooks for network management.

These hooks allow vendor modules to perform more operations
on various data streams, thereby enhancing the user's internet
experience.

'trace_android_vh_tcp_v4_connect', 'trace_android_vh_tcp_v6_connect',
'trace_android_vh_udp_v4_connect' and 'trace_android_vh_udp_v6_connect'
are invoked when a TCP or UDP stream is about to establish a
connection. The vendor module willassist in binding the stream to
different network interfaces based on additional information.
