There was a problem hiding this comment.
IMO these tests should be in test/prototype/quantization/module_swap

**Summary:** This commit adds a module-swap-based PTQ API from Quanty, including: - Quantized linear and embedding modules - `IntQuantizer` to specify how to quantize weights and activations - `CodeBookQuantizer` as an alternative to IntQuantizer - Implementation of K-means to be used for codebook quantization - Range setting and data getter utility These new APIs will complement our existing `quantize_` API, which is primarily used for tensor-subclass-based quantization today (though it can also support module swaps). All APIs introduced in this commit are under prototype and highly subject to change. In particular, we plan to delete `quantize_module_swap` and `QuantizationRecipe`, and instead integrate this flow with the `quantize_` API by creating a new `AOBaseConfig`. All code is migrated from Quanty and written by @TiRune. **Test Plan:** python test/quantization/module_swap/test_*
