Stack from ghstack (oldest at bottom):

The qdq8ta_conv2d_activations correctness tests were failing because the GPU timing collection function was filtering out quantize_and_pack_4w4c and unpack_4w4c_and_dequantize shaders from timing measurements. For these tests, these shaders ARE the operations being tested, not overhead.

This change refactors shader filtering to be configurable per test case:

  • Added shader_filter member to TestCase class with getter/setter methods
  • Created kDefaultShaderFilter (filters layout conversions + quantization) for backward compatibility
  • Created kLayoutOnlyShaderFilter (filters only layout conversions) for tests where quantization is the primary operation
  • Updated collect_gpu_timing_us() to accept shader_filter parameter
  • Updated qdq8ta_conv2d_activations to use kLayoutOnlyShaderFilter

This allows tests to control what shaders are excluded from timing measurements based on what they're actually testing, while maintaining backward compatibility for all existing tests.
