5ffc744b79 CMake: Allow disabling package version check
When building Qt repos, all find_package(Qt6) calls request a
PROJECT_VERSION version which is set in .cmake.conf via
QT_REPO_MODULE_VERSION.

This means trying to configure qtsvg from a 6.3 branch using a
6.2 qtbase won't work, because qtsvg will call find_package(Qt6 6.3)
and no such Qt6 package version exists.

There are certain scenarios where it might be useful to try to do
that though.
One of them is doing Qt development while locally mixing branches.
Another is building a 6.4 QtWebEngine against a 6.2 Qt.

Allow to opt out of the version check by configuring each Qt repo
with -DQT_NO_PACKAGE_VERSION_CHECK=TRUE. This setting is not
recorded and will have to be set again when configuring another
repo.

The version check will also be disabled by default when configuring
with the -developer-build feature. This will be recorded and embedded
into each ConfigVersion file.

If the version check is disabled, a warning will be shown mentioning
the incompatible version of a package that was found but that package
will still be accepted.
The warning will show both when building Qt or using Qt in a user
project.
The warnings can be disabled by passing
-DQT_NO_PACKAGE_VERSION_INCOMPATIBLE_WARNING=TRUE

Furthermore when building a Qt repo, another warning will show when an
incompatible package version is detected, to suggest to the Qt builder
whether they want to use the incompatible version by disabling the
version check.

Note that there are no compatibility promises when using mixed
non-matching versions. Things might not work. These options are only
provided for convenience and their users know what they are doing.

6544312869 CMake: Pass Qt6_FIND_VERSION in Qt6Config when looking for components
Pass Qt6_FIND_VERSION to components when the
find_package(Qt6 ${ver} COMPONENTS Foo) signature is used.

Create a ConfigVersion file for BuildInternals, so that BuildInternals
passes the version check.

Fix qt_configure_file to look in the _qt_6_config_cmake_dir folder for
the template file rather than Qt6_DIR, because Qt6_DIR might be
accidentally unset after a failed find_package(Qt6) call and the error
is not helpful then.

We already pass versions everywhere else when looking for
dependencies, like in ModuleDependencies.cmake.in,
PluginDependencies.cmake.in, ModuleToolsDependencies.cmake.in.

eb22826057 CMake: Fix build with CMake master / 3.22
CMake master / 3.22 introduced a behavior change in how conditions are
evaluated in the while command. It is now consistent with how if()
evaluates conditions.

This caused an issue in Qt code where a "(" opening parenthesis was
evaluated as part of the condition rather than as a string.

Fix this by wrapping the evaluation of the variable in quotes.

9f444ce533 Add a way to install versioned hard-links for tools
Add the option argument INSTALL_VERSIONED_LINK to qt_internal_add_tool
and qt_internal_add_app. For tools/apps with this argument we create an
install rule that creates a versioned hard link. For example, for
bin/qmake we create bin/qmake6.

Note that this only applies to prefix builds.

Apply this argument to qmake.
The qt_internal_add_app change is necessary for qtdiag and in qttools.

44cce1a2ea 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.
