The DPDK build script was using git to patch the DPDK repo inside
the MTL repository, which was causing undefined behavior.
Switch to patch to ensure this always works and add help for
UX.

Implement DPDK version verification to ensure MTL compatibility.
This prevents runtime crashes by validating that users are
running properly patched DPDK versions.

Known limitation: Mixed environments (e.g., patched DPDK
in Docker with unpatched system drivers) can still cause
crashes, as driver-level patches cannot be detected.
