Remove reduce_range as it is not relevant for HTP

[navsud]

Summary:
reduce_range=True reduces the available bit width by 1, in cases where quant_min, quant_max are not provided. It was originally intended for intel fbgemm kernels but I don't think this quantization setting is relevant for HTP.
Also, PTQ quantization config doesn't use it, so removing it in all the QAT configs. This helped improve the QAT model quality.

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

• pull / test-binary-size-linux-gcc / linux-job (gh) (similar failure)
  ##[error]The operation was canceled.
• Test CUDA Builds / test-executorch-cuda-build-12.8 / linux-job (gh) (detected as infra flaky with no log or failing log classifier)

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

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