Raise cmake_minimum_required in remote modules

[jhlegarreta]

Description

The dashboard is displaying configure warnings related to the cmake_minimum_required version value in remote modules, e.g.
https://open.cdash.org/builds/9713834/configure
https://open.cdash.org/builds/9713631/configure
https://open.cdash.org/builds/9716262/configure

It needs to be updated to 3.16.3 to be up-to-date with ITK, i.e.

ITK/CMakeLists.txt

Line 15 in 1381ec4

cmake_minimum_required(VERSION ${ITK_OLDEST_VALIDATED_POLICIES_VERSION}...${ITK_NEWEST_VALIDATED_POLICIES_VERSION}

ITK/CMake/ITKModuleExternal.cmake

Line 13 in 1381ec4

if(MSVC AND ${CMAKE_MINIMUM_REQUIRED_VERSION} LESS 3.16.3)
