Abtin Keshavarzian d2d9aff012 [mle] send MLE Avd on router promo & accept former child as router (#8307)
This commit updates `MleRouter to send an immediate MLE Advertisement
on promotion to `router` role and assignment of new Router ID. This
helps inform our former parent of our newly allocated Router ID and
cause it to reset it own advertisement trickle timer. This can help
speed up the dissemination of the new Router ID to other routers. It
can also help with quicker link establishment with our former parent
and other routers.

It also removes tx of multicast Link Request (including its delay
mechanism) upon promotion to `router` role.

It also updates `Mle` so if we receive an MLE advertisement from a
former child (which is recently get promoted to router) to accept it
immediately and copy the info from `Child` entry to `Router`.

Finally this commit updates the following test-cases which are
impacted by the changes above (e.g., skipping the checks for
multicast Link Request):

- `v1_2_router_5_1_1`
- `Cert_5_1_01_RouterAttach`
- `Cert_5_2_04_REEDUpgrade`
- `Cert_5_5_02_LeaderReboot`
- `Cert_5_5_05_SplitMergeREED`

# Test Purpose and Description:
# -----------------------------
# This test verifies if a device can quickly and efficiently establish links with
# neighboring routers by sending a multicast Link Request message after becoming
# a router
#
# Test Topology:
# -------------
# Leader------+
# | \ \
# Router1 Router2 Router3
# \ | |
# +---REED-----+
#
# REED should establish links to the three Routers within the delay threshold.
# The max delay consists:
# Leader may delay 1 second for MLE Advertisement
# Router may delay 1 second for MLE Advertisement
# Router may delay 1 second for MLE Link Accept after receiving MLE Link Request (multicast)
