…oat16) This diff adds support for all required scalar types in SlimTensor to support ExecuTorch aoti-driven backend usage: Int8 (Char), Int16 (Short), Int32 (Int), Int64 (Long), Bool, and BFloat16. **Key changes:** 1. **`c10/core/ScalarType.h`** - Extended with all required types: - Added enum values matching PyTorch's c10::ScalarType for compatibility - Added type alias constants (kChar, kShort, kInt, kLong, kBool, kBFloat16) - Extended `elementSize()` to return correct sizes for all types - Extended `toString()` for all types - Fixed `isFloatingType()` to include BFloat16 - Fixed `isIntegralType()` to properly handle all integral types and Bool - Added `isBoolType()` helper function - Imported BFloat16 from ExecuTorch's portable_type Differential Revision: [D89821402](https://our.internmc.facebook.com/intern/diff/D89821402/) [ghstack-poisoned]
