[api] add border_routing.h header for otBorderRouting APIs (#7877)

This commit adds `<openthread/border_routing.h`> header and moves
all the `otBorderRouting` APIs (which are related to Border Routing
Manager) into this header. It also adds a note that these APIs are
available when `OPENTHREAD_CONFIG_BORDER_ROUTING_ENABLE` is enabled.
It also adds `border_routing_api.cpp` source file for the API
implementation.

*
* All the functions in this module require `OPENTHREAD_CONFIG_BORDER_ROUTING_ENABLE` to be enabled.
*
* Border Routing Manager handles bi-directional routing between Thread network and adjacent infrastructure link (AIL).
*
* It emits ICMRv6 ND Router Advertisement (RA) messages on AIL to advertise on-link and route prefixes. It also
* processes received RA messages from infrastructure and mirrors the discovered prefixes on the Thread Network Data to
* ensure devices on Thread mesh can reach AIL through the Border Router.
*
* Routing Manager manages the Off-Mesh Routable (OMR) prefix on the Thread Network data which configures Thread
* devices with a suitable Off-Mesh Routable IPv6 address. It announces the reachability of this prefix on AIL by
* including it in the emitted RA messages as an IPv6 Route Information Option (RIO).
*
* Routing Manager also monitors and adds on-link prefix on the infrastructure network. If a router on AIL is already
* providing RA messages containing an IPv6 Prefix Information Option (PIO) that enables IPv6 devices on the link to
* self-configure their own routable unicast IPv6 address, this address can be used by Thread devices to reach AIL. If
* Border Router finds no such RA message on AIL, it generates a ULA on-link prefix which it then advertises on AIL in
* the emitted RA messages.
