Model images, keyframes and skin matrices can now be toggled.

An oversight in a previous improvement disabled writing data arrays for a JSON scene when not using the named actor map mode, which was not intended, and only tested in ParaView using the animated view export

- this commit fixes the grid-process assignment logic robust
when the number of grids cannot be exactly divided among
the number of MPI ranks (pieces in this code)
- this commit also adds MPI awareness to an existing unit test.
- the unit test TestAMReXParticlesReader is run with MPI, when enabled,
on 3 nodes. It passes only when the sum of the number of points across
all nodes is equal to a known value.
- without the change in vtkAMReXParticlesReader, the unit test will faill with MPI

(cherry picked from commit de94dced)

- this commit should allow opening files larger than 2GB on windows.
- it uses `size_t`/`vtkIdType` instead of `long` when doing stream
  operations like `seekg`, `tellg`. earlier, it passed `long` (32-bit in
  windows) to `seekg`. As a result, arrays beyond the 2GB offset could
  not be read into the buffer.

Reader regarding overlappingAMR can have an overflow issue due to his
offset. Few places in the writer should rely on vtkIdType instead of int
too.

Fixes overflows for large number of cells which can cause integer math
to overflow.
