Feature topo set improvements (issue #1060)

See merge request OpenFOAM-plus!216

type sampled is the equivalent of 'mappedField' bc
functionality - it samples a registered field on a
different region/patch/cells.

- make topoSet set/unset methods virtual to allow overloading

- old 'DELETE' enum was easily confused with 'REMOVE', which removes
  the set, not the elements from the set.

- provide corresponding subtractSet() method

STYLE: HashSet set/unset instead of insert/erase methods in topoSetSource

- simplifies switching to/from bitSet storage

- add intermediate classes topoSetCellSource, topoSetFaceSource,
  topoSetPointSource and corresponding New() factories

- Support specification with "patches" and "patch" keywords
  (similar to zone selection). Keyword "name" for compatibility.

- "boxes" has precedence over "box" (similar to treatment of "zones"
  vs "zone")

- replaces "centre", using the same keyword as other objects
  (eg, plane, rotatedBox, coordinateSystem etc).

- uses the keywords 'zones' and 'zone' to avoid potential conflicts
  with a named topoSet action, but accepts 'name' for compatibility.

- catch some dictionary entries from pre-develop branch

- make hasFaceId a top-level virtual method and remove keepIds
  equivalent from sampledTriSurfaceMesh. This makes the property
  available without casting.

- New sampling type 'none'.
  Can be used to temporarily disable a sampling surface definition,
  or to provide boilerplate for overwriting later.

COMP: fix incorrect reference in meshedSurfRef

- as part of the cleanup of dictionary access methods (c6520033)
  made the dictionary class single inheritance from IDLList<entry>.

  This eliminates any ambiguities for iterators and allows
  for simple use of range-for looping.

  Eg,
      for (const entry& e : topDict))
      {
          Info<< "entry:" << e.keyword() << " is dict:" << e.isDict() << nl;
      }

   vs

      forAllConstIter(dictionary, topDict, iter))
      {
          Info<< "entry:" << iter().keyword()
              << " is dict:" << iter().isDict() << nl;
      }

- more dictionary-like methods, enforce keyType::LITERAL for all
  lookups to avoid any spurious keyword matching.

- new readEntry, readIfPresent methods

- The get() method replaces the now deprecate lookup() method.

- Deprecate lookupOrFailsafe()
  Failsafe behaviour is now an optional parameter for lookupOrDefault,
  which makes it easier to tailor behaviour at runtime.

- output of the names is now always flatted without line-breaks.
  Thus,

     os << flatOutput(someEnumNames.names()) << nl;
     os << someEnumNames << nl;

  both generate the same output.

- Constructor now uses C-string (const char*) directly instead of
  Foam::word in its initializer_list.

- Remove special enum + initializer_list constructor form since
  it can create unbounded lookup indices.

- Removd old hasEnum, hasName forms that were provided during initial
  transition from NamedEnum.

- Added static_assert on Enum contents to restrict to enum or
  integral values.  Should not likely be using this class to enumerate
  other things since it internally uses an 'int' for its values.

  Changed volumeType accordingly to enumerate on its type (enum),
  not the class itself.

- this helps for many cases outlined in issue #1007, but can also be
  useful when simply using symlinks for shorter or reorganized
  directory structures.

Update of overRhoPimpleDyMFoam and overInterDyMFoam solvers.
Adding corresponding tutorials with best possible settings
The main effort was put on reducing pressure spikes as the
stencil change with hole cells on the background mesh.

- writes positions and a single field (eg, diameter) in plain ASCII files,
  suitable for importing in a spreadsheet or manipulation with
  scripting tools.

- code integrated from
  https://develop.openfoam.com/Community/OpenFOAM-addOns

  New name:  findObject(), cfindObject()
  Old name:  lookupObjectPtr()

      Return a const pointer or nullptr on failure.

  New name:  findObject()
  Old name:  --

      Return a non-const pointer or nullptr on failure.

  New name:  getObjectPtr()
  Old name:  lookupObjectRefPtr()

      Return a non-const pointer or nullptr on failure.
      Can be called on a const object and it will perform a
      const_cast.

- use these updated names and functionality in more places

NB: The older methods names are deprecated, but continue to be defined.
