CMake: Bump almost all cmake_minimum_required calls to 3.16 Needed for subsequent change that will check and error out if the version is lower than 3.16. We do that to ensure all policies introduced by CMake up to version 3.16 have their behavior set to NEW. Pick-to: 6.2 Task-number: QTBUG-95018 Change-Id: Ieaf82c10987dd797d86a3fd4a986a67e72de486a Reviewed-by: Kai Koehne <kai.koehne@qt.io>

Fix sub-architecture (instruction sets / SIMD) handling In qmake there are at least 2 things to know regarding sub-architectures and instruction sets. Which instruction sets does the compiler know to compile for, represented by the various config.tests and features in qtbase/configure.json. And which instructions sets are enabled by the compiler by default, represented by the configure.json "architecture" test and accessed via QT_CPU_FEATURES.$$arch qmake argument. Before this patch there was some mishandling of the above concepts in CMake code. The former can now be checked in CMake with via TEST_subarch_foo and QT_FEATURE_foo (where foo is sse2, etc). The latter can now be checked by TEST_arch_${TEST_architecture_arch}_subarch_foo (where foo is sse2, etc and the main arch is dynamyicall evaluated). The configurejson2cmake script was adjusted to take care of the above changes, and the cmake files were regenerated as well.

# FIXME: Make the this project handle a list of SIMD entries.
# FIXME: Make this project handle appending of the cflags (similar to the qmake project).
# This is needed for the x86SimdAlways configure test (
# aka we test to see if setting no SIMD (-msse2) cflags at all, will result in their implicit
# addition by the compiler).
