libMesh-level Changes

• More flexibility in transient adjoint calculations with libMesh::TimeSolver classes

• Automatic support for TIMPI+MetaPhysicL integration, which enables easier parallel communication when using Moose Automatic Differentiation

• Compatibility with stricter GCC 11 warnings, avoidance of GCC 11 optimization flag problems

• Optimizations (and for IsoGeometric Analysis problems, fixes) for calculations on element edges, including projections onto higher order elements with edge-based degrees of freedom

• Configure option to require HDF5 detection, to ease building with newer ExodusII library versions

• Bug fixes in Reduced Basis code, conversion of meshes to second order while preserving element integers

• Support for converting spline-node-based IsoGeometric Analysis meshes into unconstrained C0 rational Bernstein-Bezier form

• Side element construction caching class, optimizations
