Accelerated Build via Ninja generator with CMake

[auto-differentiation-dev]

Accelerated Continuous Integration builds with CMake using the Ninja generator:

• Faster multi-core builds on all platforms via efficient use of all cores
• Fully parallel Windows MSBuild on multi-core (was single-core before)

This replaces Makefiles and MSBuild in CI builds.

The CMakePresets for Windows local builds have also been adjusted, as Visual Studio ships with the Ninja builder, so that developers benefit from this change too.

Any idea why the license/cla check is still listed as expected, even though this has been signed before?

[lballabio]

It happens — sometimes the cla check has a glitch and needs a manual push.
