[SYCL][Graph] Reenable L0 interop test on PVC

Re-enable the interop-level-zero-launch-kernel.cpp E2E test on
PVC by making the following correctness changes to the native L0 code:

* Both `zeKernelSetGroupSize` and `ZeGroupCount` were set to have 1024 in the X
  dimensions when this is the total size of the USM allocation, and therefore
  the number of work items we want. Updated to use `zeKernelSuggestGroupSize`
  to work calculate the correct group sizes and count.
* Update `zeKernelSetArgumentValue` call so that the size parameter is the size
  of the pointer rather than size of the USM allocation.
