[mle] add RLOC16 related helper methods in Mle (#10440)

Browse Source 
This commit introduces new helper methods in the `Mle` class:

- `HasRloc16()`: Checks if the device is using a given RLOC16.
- `MatchesRouterId()`: Checks if this device's RLOC16 matches a given
  Router ID.
- `HasMatchingRouterIdWith()`: Checks if this device's RLOC16 shares
  the same Router ID with a given RLOC16. This implies that the two
  devices are either directly related as parent and child or are
  children of the same parent within the Thread network.
- `ParentRloc16ForRloc16()` derives the router RLOC16 corresponding to
  the parent of a given (child) RLOC16.

These methods act as syntactic sugar, simplifying code and enhancing
readability.
