test: add e2e validation for MANA accelerated networking

[titilambert]

What this PR does / why we need it:

Adds end-to-end tests validating that MANA (Microsoft Azure Network Adapter)
accelerated networking is properly configured on V6 VM series. The tests cover
Ubuntu 22.04, Ubuntu 24.04, and Azure Linux V3.

Validations added:

• MANA PCI device (00ba) is exposed to the VM
• MANA kernel driver (mana.ko) is loaded
• Virtual Function (VF) interface is bonded to eth0
• Network traffic actually flows through the VF path

Additionally, MANA validation is run conditionally in ValidateCommonLinux
on any VM where MANA hardware is detected (V5+ series).

Pull request overview

Adds end-to-end validation for MANA (Microsoft Azure Network Adapter) accelerated networking on newer VM series, expanding the e2e suite to assert both device/driver presence and datapath correctness on Ubuntu 22.04/24.04 and Azure Linux V3.

Changes:

• Added VMSS helper to explicitly enable Accelerated Networking on the primary NIC for targeted MANA scenarios.
• Introduced MANA validation helpers (PCI device, driver availability, VF bonding, VF traffic counters) and conditionally ran them from ValidateCommonLinux when MANA hardware is detected.
• Added dedicated e2e scenarios for Ubuntu 22.04, Ubuntu 24.04, and Azure Linux V3 on a V6 SKU, plus a new Tags.MANA filter flag.
