The API `createRandomizedDataset()` randomly selects a channel
between channel 11 and 26. But not all countries support channels
between 11 and 26.

This CL selects random channel from  the preferred channel mask if
the preferred channel mask is not 0, otherwise choose one from the
supported channel mask.

  Add CTS test for Multipacket Known-Answer Suppression
  Add CTS test for Known-Answer Suppression

This change is a follow-up from aosp/2970991. The kernel bug
can trigger crashes on some T devices. Therefore, bumping the
required API level is necessary.
No CTS modification since the check doesn't exist in
pre-U CTS releases.

This test case lets the BR send a UDP message to Thread device using
socket API and verify the message is received on the Thread device via
ot-ctl udp command.

For now this only verifies the direction BR -> ED because the other
direction ED -> BR is depending on platform UDP feature which is not
enabled yet.
