Validate interface name length in CLI

[stepanblyschak]

This PR is accompanied by sonic-net/sonic-swss-common#931 and sonic-net/sonic-buildimage#20108

What I did

Validate interface name length does not exceed the limitation of IFNAMSIZ to align to kernel restrictions.

How I did it

Add validation checks in the relevant config functions for the following interface types:

vxlan
vlan
vrf
loopback
subinterface
portchannel

How to verify it

UT tests added

Previous command output (if the output of a command-line utility has changed)
New command output (if the output of a command-line utility has changed)

@qiluo-msft @wangxin Could you please help with static analysis? Static analysis fails but I do not see a problem:

config/main.py:7937:21: E128 continuation line under-indented for visual indent

But line 7937 is not even in the diff.

And here I do not see any tabs on those lines in my diff:
