[OpenMP] Lower printf to __llvm_omp_vprintf
Extension of D112504. Lower amdgpu printf to `__llvm_omp_vprintf`
which takes the same const char*, void* arguments as cuda vprintf and also
passes the size of the void* alloca which will be needed by a non-stub
implementation of `__llvm_omp_vprintf` for amdgpu.
This removes the amdgpu link error on any printf in a target region in favour
of silently compiling code that doesn't print anything to stdout.

[OpenMP] Fix bug 50022
Bug 50022 [0] reports target nowait fails in certain case, which is added in this
patch. The root cause of the failure is, when the second task is created, its
parent's `td_incomplete_child_tasks` will not be incremented because there is no
parallel region here thus its team is serialized. Therefore, when the initial
thread is waiting for its unfinished children tasks, it thought there is only
one, the first task, because it is hidden helper task, so it is tracked. The
second task will only be pushed to the queue when the first task is finished.
However, when the first task finishes, it first decrements the counter of its
parent, and then release dependences. Once the counter is decremented, the thread
will move on because its counter is reset, but actually, the second task has not
been executed at all. As a result, since in this case, the main function finishes,
then `libomp` starts to destroy. When the second task is pushed somewhere, all
some of the structures might already have already been destroyed, then anything
could happen.
This patch simply moves `__kmp_release_deps` ahead of decrement of the counter.
In this way, we can make sure that the initial thread is aware of the existence
of another task(s) so it will not move on. In addition, in order to tackle
dependence chain starting with hidden helper thread, when hidden helper task is
encountered, we force the task to release dependences.
