Use ECMInstalledLibraryCheck

Needs extra-cmake-modules!590 (merged) (see also now published online docs or related blog port)

For a better idea of what the added function calls calls provide in their effort to simulate the consumer view on the installed development artifacts, see below the content of the generated CMakeLists.txt file (in build subdir src/KF6TextEditor_ECMInstalledLibraryCheck), which also injects some checks for certain variables and macros.

The check is invoked by the build target all_installed_library_check (to be done post-installation only), the evaluation currently is as primitive as requiring the build to pass, any issues found have to be taken from the build log.
