[SYCL][ESIMD][EMU] Removing 'XFAIL' markings for 'single_task' tests (#910)

* [SYCL][ESIMD][EMU] Removing 'XFAIL' markings for 'single_task' tests

- 'single_task()' is enabled for ESIMD_EMULATOR backend in intel/llvm

* Comment update for newly discovered failure after 'single_task()' enabled

* Preparing enabling ESIMD_EMULATOR during CI
