Subject: [PATCH] Raise CMake minimum to 3.16...3.30 range, cleanup lower
 minimums in subdirs

ECM Find* and Qt6 CMake modules already require 3.16, so it is a good
base line. CMake 3.16 was released in 2019. At the same time, defining
the range to 3.30 means the build system is already being tested with
all of the Policy changes up to build time CMake version <=3.30 enacted.
3.30 is picked as CMP0175 (in 3.31) introduced an error in <ECM-6.20
KDEClangFormat, and ECM commit 24fa7e53b054f81f44b5b00257bd97631200503d
is not backported in kf5 branch.

Successfully tested with CMake 4.1.2.
