Pull request: SYCL: Move CPY kernels to a separate file and add few missing kernels

Moved the CPY kernels to a separate file for better maintainability as well as tried to add few missing type conversation kernels including dequant cpy kernels:

- Q8_0 -> F32
- Q4_0 -> F32
- Q4_1 -> F32
- F32 -> Q5_0
- Q5_0 -> F32
- F32 -> Q5_1
- Q5_1 -> F32
- F32 -> IQ4_NL

Updated the backend device support check in ggml-sycl.cpp to enable these new type combinations.

Locally, the test-backend-ops is passing with this change.
