Mark headers to be excluded from header style tests

Add a comment to the bottom of each header that used to be excluded from
kit HeaderTesting tests in monolithic VTK.  Format the comment in a way
that cannot be accidentally copied into another header without
modification.  This comment will tell HeaderTesting.py to exclude a
header from testing so we do not have to separately list every excluded
header in every module.
