[mle] add DeviceRole type, and IsChild, IsRouter, etc method (#4794)

Browse Source 
This commit defines a new enum type `Mle::DeviceRole` mirroring the
public `otDeviceRole` enumeration. The enumerator in the new type
follow `kRole{Value}` style and intended for use in the core modules.
It also adds helper method in `Mle`, `IsChild()`, `IsRouter()`,
`IsLeader()`, etc to check the current device role.
