Followup of apache#15305 , this PR creates API to query device L2 cache size in bytes. Currently, the API-supported devices includes CUDA, OpenCL, and ROCM. Note that OpenCL's API does not return the accurate device L2 cache size. I cannot find a Vulkan API that returns L2 texture cache size, but the `vkCmdPipelineBarrier` call will flush the L2 texture cache automatically(https://zeux.io/2020/02/27/writing-an-efficient-vulkan-renderer/), thus we return 0 by default.
