[slimtensor] Add from_etensor factory function for ETensor to SlimTensor conversion#16996

Pull Request resolved: #16469 This diff updates the slimtensor file names to follow ET style (use under_score instead of Camel). Note that we keep the c10 files as Camel since et/c10 files are also in Camel Case. ghstack-source-id: 336658382 @exported-using-ghexport Differential Revision: [D90143740](https://our.internmc.facebook.com/intern/diff/D90143740/)
…sor conversion Pull Request resolved: #16551 Add from_etensor() factory function that creates a SlimTensor from an ExecuTorch portable tensor (ETensor), copying data to a target device. Key features: - Handles int32_t to int64_t conversion for sizes/strides (ETensor uses int32_t, SlimTensor uses int64_t) - Supports CPU and CUDA target devices via storage()->copy_() - Preserves tensor strides (non-contiguous layouts) - Provides both reference and pointer overloads ghstack-source-id: 336658383 @exported-using-ghexport Differential Revision: [D90539554](https://our.internmc.facebook.com/intern/diff/D90539554/)
