[trel] implementing Thread Radio Encapsulation Link (TREL) (#4440)

Browse Source 
This commit implements TREL protocol to encapsulate and exchange IEEE
802.15.4 frames over a packet switched network (e.g., a wireless LAN).
This commit also provides a TREL IPv6/UDP interface implementation
(using link-local IPv6 unicast/multicast addresses to communicate over
a subnet). It defines a platform abstraction (`otPlatTrelUdp6*`) for
TREL over IPv6/UDP.

This commit also provides an implementation of the TREL platform under
`examples/posix` focusing on simulating the behavior of the link.
