[SYCL] Fix SYCL im2col and convert Overflow with Large Dims (#9052)
* sycl: fix im2col overflow and sync with cuda Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * sycl: fix convert overflow Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * sycl: fix convert and dequantize Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * sycl: fix ib in dmmv Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * sycl:refine convert Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * sycl: move downsample global_range into common Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * test: add im2col and convert test cases Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * test: make new cases only in sycl Signed-off-by: zhentaoyu <zhentao.yu@intel.com> * test: comment new test_cases for only local testing Signed-off-by: zhentaoyu <zhentao.yu@intel.com> --------- Signed-off-by: zhentaoyu <zhentao.yu@intel.com>
