ENH: Paint checkbox in QHeaderView

Added new class that derives from QHeaderView and paints a checkbox on the
section header if the individual model items are checkable.
Currently the class is used in pqTreeView and needs to be standardized across
all views and widgets.
Removed old unused pqCheckableHeaderView and pqCheckableHeaderModel classes.
This fixes issue 14580.

Setting a better compressor for animation exporting

The VTK-default "MSVC" codec is old and has poor compression ratios.
Some research seems to indicate that "MP43" is supported on XP and is
at least half decent[1].

cmake: Use ${var} instead of @var@

The latter works, but is not widely used or known. CMake with CMP0052
set will not expand it, so replace it with ${var}.
