[OpenMP][FIX] Ensure to determine aligned regions properly

There were missing checks in the aligned region code, copy-paste errors
(= usage of the IsReachedFromAlignedBarrierOnly value instead of
IsReachingAlignedBarrierOnly value on the forward pass), and a missing
update of the call state for sync declarations and definitions.

Partially fixes https://github.com/llvm/llvm-project/issues/60425
