…igurable shader filtering 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.
