LOG: [Clang] [OMPIRBuilder] Prevent Null Pointer Dereference in OpenMP IR Builder (#115506)

This commit addresses Static Analyzer issues related to potential null
dereference by replacing dyn_cast<> with cast<> in OMPIRBuilder.cpp to
ensure that ArgStructType is not null before it is used, improving the
stability and reliability of the code.
