zebra: Send correct default vrf tableid for MROUTE stats
So the linux kernel uses the RT_TABLE_MAIN for the table
id used for ip routing. The multicast routing tables use
RT_TABLE_DEFAULT. We changed the internal code of zebra_vrf

zebra: When registering a nexthop, we do not always need to re-eval
The code prior to this change, was allowing clients to register
for nexthop tracking. Then zebra would look up the rnh and
send to that particular client any known data. Additionally
zebra was blindly re-evaluating the rnh for every registration.
This leads to interesting behavior in that all people registered
for that nexthop will get callbacks even if nothing changes.
Modify the code to know if we have evaluated the rnh or not
and if so limit the re-evaluation to when absolutely necessary
This is of particular importance to do because of nht callbacks
for protocols cause those protocols to do not insignificant
work and as more protocols are registering for nht callbacks
we will cause more work than is necessary.

ospfd: interface speed change during intf add
The problem is seen where speed mismatch caused ECMP route

During cold boot, some interface speed updated by zebra as

In this case, ospf already have created interface (bond interface),
but speed was not updated, trigger to do interface speed change
as part of interface add, which will trigger all Router LSA to
use updated speed into cost calculation.
Ticket:CM-22170
Testing Done:
Bring up CLOS config with Spine and leafs. Leaf have CLAG pair,

At spine one of the bond connecting to leaf node was having
higher speed than the paired device, With this fix, at spine (DUT)
