Frr 8.2 upgrade (#10691)

Browse Source 
Why I did it
Upgrade FRR to version 8.2.2. Build libyang2 required by FRR.

How I did it
Update FRR version and tag.

How to verify it
Following tests were performed on sonic-vs:

BGP docker status check
BGP configuration and session establishment
Route redistribution and ping
Issued show commands to check the bgp neighbor and routes
Checked app-db to ensure bgp routes are installed with correct interface and nexthop.
Create VRF and check FRR knows the VRF
Check VRF routes are installed in app-db with correct Vrf name and next-hop
Establish BGP Evpn session and check if Evpn routes (multicast, mac, prefix) are exchanged and installed correctly in app-db.

Subject: [PATCH] [PATCH 6/8] [frr] remove frr log outchannel to /var/log/frr.log
SONiC runs frr inside a docker and the logs are sent to base image
via rsyslog and recorded already. There is no need to keep the
frr.log inside the docker. It will grow and take all harddrive
space eventually.

Subject: [PATCH] Add "bgp bestpath peer-type multipath-relax"
This new BGP configuration is akin to "bgp bestpath aspath
multipath-relax". When applied, paths learned from different peer types
will be eligible to be considered for multipath (ECMP). Paths from all
of eBGP, iBGP, and confederation peers may be included in multipaths
if they are otherwise equal cost.
This change preserves the existing bestpath behavior of step 10's result
being returned, not the result from steps 8 and 9, in the case where
both 8+9 and 10 determine a winner.
When "bgp bestpath peer-type multipath-relax" is enabled, multipaths
with both eBGP and iBGP learned routes may exist. It is not desirable
for the iBGP next hops to be discarded from the FIB because they are not
directly connected. When publishing a nexthop group to zebra, the
ZEBRA_FLAG_ALLOW_RECURSION flag is normally not set when the best path
is eBGP; when "bgp bestpath aspath multipath-relax" is configured, the
flag will now be set if any paths are from iBGP peers. This leaves
all-eBGP multipaths still requiring nexthops over connected routes.
