[SYCL] rename GGML_SYCL_SUPPORT_LEVEL_ZERO (#24719)

Browse Source 
* rename GGML_SYCL_SUPPORT_LEVEL_ZERO to GGML_SYCL_SUPPORT_LEVEL_ZERO_API, and GGML_SYCL_ENABLE_LEVEL_ZERO to  GGML_SYCL_USE_LEVEL_ZERO_API

* fix code format

* fix error when rebase

Requires Level Zero headers/library at build time and Intel GPU driver (Level Zero runtime) at run time. Reduces system RAM usage during multi-GPU inference.
