Stack from ghstack (oldest at bottom):

This change adds a reference_graph parameter to the calculate_numeric_gap API, allowing users to explicitly select which graph to use as the golden reference for numeric gap calculation, which enables backends like Qualcomm to use the post-custom-transform graph as the golden reference for numeric gap calculation.

This is part of the operator-level numeric discrepancy detector project for ExecuTorch Qualcomm backend (#16381).
