What I did
Updated checks for PORT entry in STATE_DB in vlanmgrd additionally check for presence of "state" attribute.

Why I did it
Prior to recent commits for PORT auto-negotiation, 3 daemons in cfgmgr (portmgrd, teammgrd, and intfmgrd) would not allow configuration to proceed for a specific PORT until portsyncd detected the presence of the kernel device (EthernetN) associated with the PORT and created the associated entry for the PORT in the STATE_DB with attribute "state" and value "ok".
With recent commits for PORT auto-negotiation, this logic is now broken due to creation of PORT entry in the STATE_DB by PortsOrch with only "supported_speed" attribute.

How I verified it
This leads to the issue where vlanmgrd might try to access the port even without it created
Oct 21 07:51:42.121276 arc-switch1025 ERR swss#vlanmgrd: :- main: Runtime error: /bin/bash -c "/sbin/ip link set "Ethernet10" master Bridge && /sbin/bridge vlan del vid 1 dev "Ethernet10" && /sbin/bridge vlan add vid 1000 dev "Ethernet10" pvid untagged" :

**What I did**

Avoid removing a VRF routing table when there are pending creation entries in gRouteBulker

1. Remove a VRF routing table when a routing entry is removed only if there is no pending creation entry in gRouteBulker
2. Avoid uninitialized value SAI IP address/prefix structure

**Why I did it**

Fix issue: out of range exception can be thrown in `addRoutePost` due to non exist VRF

```

**How I verified it**

Unit (mock) test

**Details if related**

Originally, it cleaned up a VRF routing table whenever a prefix of the VRF was removed if
1. there was no routing entry in the VRF routing table and
2. the prefix was not pending creation in gRouteBulker

The motivation is to remove a VRF routing table if there is no routing entry in the VRF and no routing entry pending creation for that VRF. However, condition 2 does not guarantee that.

The ideal way of the 2nd condition is to check pending creation entries of a certain VRF, which we can not do.
So, we are using strict conditions here as the following:
1. there is no routing entry in the VRF routing table and
2. there is no pending creating routing entry in gRouteBulker regardless of which VRF it belongs to
