[routing-manager] add mIsReachable to otBorderRoutingRouterEntry (#10388)

Browse Source 
This commit adds `mIsReachable` to the `otBorderRoutingRouterEntry`
structure to indicate whether a router is reachable. A router is
marked unreachable after it fails to respond to multiple Neighbor
Solicitation (NS) probes. Additionally, the `br` CLI commands are
updated to display this information.
