usb: implement heuristics to flag data compliance warnings

Browse source 
Support flagging enum failure and flaky connection in device mode,
flagging enum failure and missing data lines in host mode.
No warning would be flagged until 5 secs after the data session
starts to give ample time for the connection to stabilize, a timer
is added to support it.

Bug: 296119135
Test: manually trigger the warnings
