text: Title: Remove Direct Arm Compute Libray (ACL) Integration for Quantized Matmuls: `qlinear`/`qlinear_dynamic`
  Body: PR https://github.com/pytorch/pytorch/pull/148585 (temporarily) introduced a direct ACL implementation for `qlinear` and `qlinear_dynamic` for AArch64 when `USE_MKLDNN_ACL` is set.
  This direct ACL implementation is a lot faster than the existing implementations that utilized ACL through oneDNN (MKLDNN) due to the (current) API friction between the stateful ACL API and the stateless oneDNN API (see benchmarks and numbers on https://github.com/pytorch/pytorch/pull/148585).
  
  I'm creating this issue to make sure that we end up removing this direct ACL path for `qlinear` and `qlinear_dynamic` once we're done enabling a fast implementation for quantized matmuls through oneDNN+ACL.
