build: CMake 4.1.2 for the runtime native build (#2051)

The SDK repository's stable channel now offers CMake 4.1.2, and the runtime's CMakeLists only asks for 3.18.1, above the 3.5 floor CMake 4 still accepts. Only the runtime AAR build here uses this version; the scripts shipped to apps never invoke CMake.
