15e81fa4 - [SYCL] Refine annotated_ptr address space based on compile-time USM kind (#11623)

[SYCL] Refine annotated_ptr address space based on compile-time USM kind (#11623) Right now the annotated_ptr extension applies compile-time properties on `decorated_global_ptr` for SYCL device code. As the SYCL extension [sycl_ext_oneapi_usm_malloc_properties](https://github.com/intel/llvm/blob/sycl/sycl/doc/extensions/proposed/sycl_ext_oneapi_usm_malloc_properties.asciidoc#sycl_ext_oneapi_usm_malloc_properties) introduces compile-time property "usm_kind"(implemented in #10235 ), this PR further refines the address space of this pointer (using `decorated_device_ptr` or `decorated_host_ptr`) when 1. `usm_kind` property is specified in annotated_ptr type, and 2. both `__SYCL_DEVICE_ONLY__` and `__ENABLE_USM_ADDR_SPACE__` are turned on (i.e. requiring compiler flags "-fsycl-device-only -fsycl-targets=spir64_fpga") Other changes: - move `annotated_ptr.hpp` out from `annotated_arg` file into a separate folder - add new header file `annotated_ptr_properties.hpp` for annotated_ptr specific properties
