cmake: upgrade 3.31.6 -> 4.0.3

This is the first major release bump for CMake since 3.0 was released in 2014.
Compatibility with versions of CMake older than 3.5 has been removed. Full
release notes are available at [0].

Obsolete patches have been removed and the few remaining ones have been
refreshed. We can now build cmake without patches, only cmake-native requires
two that are not suitable for upstreaming.

The main license file has been renamed from Copyright.txt to LICENSE.rst in [1].
References to the file have been updated, causing changes to the licensing
header in 'cmake.h' (see [2]).

Additionally, the '1996 - 2024' copyright statement in (cm)curl's COPYING was
updated to '1996 - 2025' in [3].
