migrate jarvis quant-per-tensor hifi ops to oss (#6293)

Summary:
Pull Request resolved: #6293

- only migrated **quant-per-tensor** in this diff. will do the rest of 3 in the stack
- solved the --start-lib --end-lib option not recognized in here - need to import libs from //executorch. Nothing do with the cxx wrapper in buck
- aligned namespace to **cadence::impl:HIFI::native and cadence::impl:HIFI::kernel**
- kernel to be removed after all ops are migrated
