[SYCL] Use copy engine for memory read/write operations

[asudarsa]

In the present state of the L0 plugin, MemBufferWrite and MemBufferRead operations are being executed using compute engines. This patch changes this behavior for the operations to be executed using copy engines.
It is expected to improve performance.

Thanks
