[ET-VK][ez] Accept sample_kwargs as an argument in several test util functions

[SS-JIA]

Stack from ghstack (oldest at bottom):

• [ET-VK] Introduce specialized implementation for per-row reduction #15161
• [ET-VK] Contiguous buffer implementation for embedding #15160
• [ET-VK] Implementation of pow.Tensor_Scalar #15159
• [ET-VK][ez] Introduce a graph config setting to force resize functions to execute #15158
• [ET-VK] Introduce TextureMetadata struct #15157
• [ET-VK][ez] Allow bool tensors to be lowered to ET-VK and add uint8(bool) dtype variants for several compute shaders #15155
• [ET-VK][ez] Make pipeline executable properties be controlled by a different macro #15154
• -> [ET-VK][ez] Accept sample_kwargs as an argument in several test util functions #15153

Title says it all! This makes it possible to export models that require kwargs to be defined instead of args.

NEW FAILURES - The following jobs have failed:

• pull / unittest-arm-backend-with-no-fvp (test_pytest_models) / linux-job (gh)
  RuntimeError: Command docker exec -t 3645126ac13033a748427a719e07ff4275005895964f1880ab6cda3f7c712663 /exec failed with exit code 1

FLAKY - The following jobs failed but were likely due to flakiness present on trunk:

• pull / test-models-linux (ic3, portable, linux.2xlarge) / linux-job (gh) (matched linux rule in flaky-rules.json)
  The runner has received a shutdown signal. This can happen when the runner service is stopped, or a manually started runner is canceled.
• pull / unittest-editable / linux / linux-job (gh) (detected as infra flaky with no log or failing log classifier)

BROKEN TRUNK - The following job failed but were present on the merge base:

👉 Rebase onto the `viable/strict` branch to avoid these failures

• pull / unittest / linux / linux-job (gh) (trunk failure)
