cmake: Bump minimum required CMake version to 3.22

Browse Source 
Ubuntu 20.04 LTS has reached the end of standard support. There no
longer appear to be compelling reasons to maintain compatibility with
CMake 3.16.
The new suggested minimum, CMake 3.22, is shipped with Ubuntu 22.04 LTS,
which is supported until April 2027.

This change also introduces new CMake policies, from CMP0098 to CMP0128.
