Autogen: Add and use cmQtAutoGenInitializer::InfoWriter class

The new ``cmQtAutoGenInitializer::InfoWriter`` class provides an interface to write strings/vectors/sets/maps in CMake format into a file. Its use replaces various `cmJoin` calls that failed to address escaping of semicolons in list elements. Closes #18554
