ENH: use offsets from CoherentMesh to remove communication (globalIndex) in OFCstream::writeGlobalGeometricField

- this needs closing and re-opening the file because ADIOS2 does not implement flushing for BP5
https://github.com/ornladios/ADIOS2/issues/3060

- default behaviour is one data.bp per time folder
setting writeBulkData in controlDict writes one case-global data.bp

- the develop branch requires an autoconf version newer than may be
  available on the user's system

- Also optimizations in creation of coherent mesh -- domainDecomposition::parallelMesh()
- Also optimizations in polyMesh::write() when in coherent format and the associated work in construction of SlicePermutation.

- unifying subset identification for processor patch construction in CoherentMesh
- Offsets as iterable of pairs
- Offsets construction with globalIndex
- move processor patch communication into CoherentMesh as member functions
- separating permutations into SlicePermutation and FragmentPermutation (SRP)
- add sliceWritePrimitives for const label* data
- removing and refactoring redundant functionality

- replace constexpr-if constructs
- replace std::make_unique
- replace generic lamdas
- add trailing return type with automatic return types
- simplified is_range type trait

- allows selection of different system compilers.
  Eg,

     export WM_COMPILER=Gcc
     export WM_COMPILE_CONTROL="version=11"

  will use gcc-11 and g++-11 for compilation

ENH: naive decomposition on-the-fly if the size of partitionStarts does not fit to the number of MPI ranks, i.e. if not present at all
BUG: proper checkOut of boundary_ in polyMesh

- COHERENT: worse formatting but readable.
