Fix AOCC shadow warning and VTK global ID SIGFPE

[sushma-4]

Pushed some changes that were needed to succesfully compile and pass unit tests in our environment (AOCC Compiler, AOCL).

1. src/coreComponents/physicsSolvers/solidMechanics/contact/SolidMechanicsAugmentedLagrangianContact.cpp - No functional behavior changes, only the capture variable name is updated to avoid shadowing the class member m_symmetric. AOCC treats the warning as an error due to -Werror=shadow
2. src/coreComponents/mesh/generators/VTKUtilities.cpp - testSinglePhaseMFDPolyhedral failed intermittently during mesh initialization. The failures occurred before solver setup and consistently originated from VTK while generating GlobalIds. Hence, Wrapping the call to vtkGenerateGlobalIds::Update() with LvArray::system::FloatingPointExceptionGuard to temporarily disable FPE trapping
