[CI][CODEOWNERS] Change CODEOWNERS of `sycl/test-e2e/LLVMIntrinsicLow…

…ering/*` to intel/dpcpp-spirv-reviewers (intel#16067)

Currently, the owners of
[sycl/test-e2e/LLVMIntrinsicLowering/*](https://github.com/intel/llvm/tree/sycl/sycl/test-e2e/LLVMIntrinsicLowering)
are SYCL RT reviewers but I see that all the test cases here related to
llvm-spirv.
I propose changing the code owners of these tests to
intel/dpcpp-spirv-reviewers instead.
