CMake: Split QtBuild.cmake into smaller files
QtBuild.cmake is huge. Split it.
Move module, plugin, tools, executables and test related functions out
of QtBuild.cmake into separate files.
Do the same for many other things too.
An additional requirement is that all the new Helpers files only
define functions and macros.
No global variable definitions are allowed, nor execution of commands
with side effects.
Some notes:
qt_install_qml_files is removed because it's dead code.
Some functions still need to be figured out, because they are
interspersed and depend on various global state assignments.
Task-number: QTBUG-86035
