Fix nxos modules idempotence issue (#46437)

* nxos_interface vlan and port-channel idempotence fix for mtu

* Fix MTU reconfiguration at each execution

* nxos_interface port-channel idempotence fix for mode (#44248)

* Fix trunk mode idempotence for port-channel
* Gather ethernet and port-channel code for mode management

* nxos_linkagg port-channel idempotence fix for channel-group's mode

The regex to retrieve channel-group's mode is not enough accurate.
Therefore, the swhitchport mode  was matched instead of the
channel-group's mode.

* This fix add accuracy to match the right configuration command

* Add support for switchport mode dot1q-tunnel in nxos_interface

* Fix layer reconfiguration at each execution

(cherry picked from commit c51407c806)
