vtkDataArray: split implementation into separate files

Array dispatching significantly increases compile time. Using clang, the prior vtkDataArray.cxx took almost 5 minutes to compile. By splitting out the implementations into separate files, overall compilation time is now 77 seconds on the same hardware (with 14 workers).

Sample timings (sample size of 1):

Time to complete CommonCore:

Before:  08:06.120
After:   05:03.382

Individual objects:

Before:

   04:51.551   vtkDataArray.cxx.o

   00:01.746   vtkDataArray.cxx.o
