Adds the callbacks for ordered with source/sink dependencies.
The test for task dependencies changed, because callbach.h now actually prints

The OpenMP spec has the task-fulfill event for a call to omp_fulfill_event.
If the task did not yet finish execution, ompt_task_early_fulfill is used,
otherwise ompt_task_late_fulfill.
If a task does not complete, when the execution finishes (i.e., the task goes
in detached mode), ompt_task_detach instead of ompt_task_complete must be
used, when the next task is scheduled.
A test for both cases is included, which only work with clang-11+

This is done at call-site and does not need to be handled in
__kmp_invoke_microtask. It was already absent from the x86
and x86_64 assembly, this patch removes it from the generic
implementation in z_Linux_util.cpp and adds documentation for
AArch64 and PPC64 that it's actually not needed. I can't test
on these architectures, so I don't want to change the code just
because it looks right :)
While at it, rename some variables for consistency and add a
check in test/ompt/parallel/normal.c that the pointer was reset
before entering the barrier.

Summary:
I have discovered this because i wanted to experiment with
building static libomp (with openmp-4.0 support only)
for debugging purposes.
There are three kinds of problems here:
1. `__kmp_compare_and_store_acq()` simply does not exist.
It was added in D47903 by @jlpeyton.
I'm guessing `__kmp_atomic_compare_store_acq()` was meant.
2. In `__kmp_is_ticket_lock_initialized()`,
`lck->lk.initialized` is `std::atomic<bool>`,
while `lck` is `kmp_ticket_lock_t *`.
Naturally, they can't be equality-compared.
Either, it should return the value read from `lck->lk.initialized`,
or do what `__kmp_is_queuing_lock_initialized()` does,
compare the passed pointer with the field in the struct
pointed by the pointer. I think the latter is correct-er choice here.
3. Tests were not versioned.
They assume that `LIBOMP_OMP_VERSION` is at the latest version.
This does not touch LIBOMP_OMP_VERSION=30. That is still broken.

than the scheduling events of the tasks are tested. Thus, the order of
