Some of the enqueued operations are implemented directly in the Level Zero plugin (e.g. map/unmap) and their implementation does not satisfy in-order queue requirements, leading to incorrect behaviour if the event dependencies that should be redundant are dropped. Restore these event dependencies until this is fixed in the Level Zero plugin.

…#139) The test was initially disabled due to a bug in the Level Zero plugin that led to a hang, which has already been fixed in intel/llvm#3081 Despite that, the test should stay disabled since the tested functionality is to be temporarily turned off for Level Zero in intel/llvm#3188

… unsigned (#3188) Per SPIR-V OpenCL.ExtendedInstructionSet spec, the num_elements arg must be size_t. So this PR changes its type to unsigned in SPV-IR. Adding const to pointer arg aligns with OpenCL spec and allows const pointer input. Original commit: KhronosGroup/SPIRV-LLVM-Translator@96f5ade29c9088e
