Summary: Wire up the VGF backend using the pre-built Arm MLSDK artifacts from third-party/toolchains/arm-mlsdk (added in the parent diff). The absence of support of these vgf tests was causing painful scenarios where Executorch Arm/TOSA changes would pass on fbsource then break github CI when merged, because we did not support running vgf emulation at MEta, but opens ource github did support it ([example](https://github.com/pytorch/executorch/actions/runs/23659213665/job/68924697568?pr=18529)).
