feat(kernel-hwe): Enable vmxnet3

[rlmenge]

BB: https://dev.azure.com/mariner-org/mariner/_build/results?buildId=1157116&view=results

Enable the VMware VMXNET3 network driver in the Azure Linux 3 HWE kernel on x86_64.

Changes

• Set CONFIG_VMXNET3=y for the x86_64 kernel-hwe configuration.
• Explicitly disable CONFIG_INFINIBAND_VMWARE_PVRDMA, which becomes visible after enabling VMXNET3.
• Leave VMXNET3 disabled on arm64 because it is unavailable for that architecture.
• Update kernel-HWE config signatures.
• Bump the kernel-HWE release and related packages.
• Add VMXNET3 requirements to the kernel config checker:
  • x86_64: y
  • arm64: n

Fixes AB#22300
