  • STYLE: Add itkVirtualGetNameOfClassMacro + itkOverrideGetNameOfClassMacro
  • STYLE: Replace itkStaticConstMacro with static constexpr

Added two new macro's, intended to replace the old 'itkTypeMacro' and
'itkTypeMacroNoParent'.

The main aim is to be clearer about what those macro's do: add a virtual
'GetNameOfClass()' member function and override it. Unlike 'itkTypeMacro',
'itkOverrideGetNameOfClassMacro' does not have a 'superclass' parameter, as it
was not used anyway.

Note that originally 'itkTypeMacro' did not use its 'superclass' parameter
either, looking at commit 699b66cb04d410e555656828e8892107add38ccb, Will
Schroeder, June 27, 2001:

Use static constexpr directly now that C++11 conformance
is required by all compilers.

'itkStaticConstMacro(name, type, value)' became unconditionally
identical to 'static constexpr type name = value' with ITK commit

'itkGetStaticConstMacro(name)' became unconditionally identical to
'(Self::name)' with ITK commit 84e490b81e3f3c2b0edb89ae7b9de53bfc52f2b2
"Removing some outdated compiler conditionals", Hans Johnson, 31 July
2010.

Most 'itkStaticConstMacro' calls were removed by ITK commit 5c14741e1e063a132ea7e7ee69c5bd0a4e49af74
The convention of only specifying the MAJOR version
is the indicator that the latest version in that
series should be used.

By not specifying the MINOR and PATCH, the exact versions
is not pinned, but the latest in that series is chosen.
(i.e. the v5 tag is updated every time a new MINOR or PATCH
tag is generated).

This allows benefiting from minor patch fixes without needing
to update workflows.
