CMake: Add support for overriding Qt6ConfigVersion.cmake

In QtWebEngine we would like to support the following syntax:

  find_package(Qt6 6.140 COMPONENTS WebEngineCore ...)

The idea is that the above call should only work
if the requested version is specified exclusively for QtWebEngine
components (WebEngineCore, WebEngineWidgets or WebEngineQuick).

Adding any other component will fail as the version would be ambiguous.
If the call does not match the above requirements, it would simply
include the base Qt6ConfigVersionImpl file.

To allow that, Qt6ConfigVersion.cmake should support being overridden.

Add an ALLOW_OVERRIDE_FILES to
qt_internal_write_qt_package_version_file and use it for the Qt6 call.

This injects additional code into the
'Qt6<module>ConfigVersion.cmake' file
which globs ConfigVersionOverrides dir for special override
files and includes them.

The override files should be called according to the scheme:
Qt6<module>ConfigVersionOverride_[0-9][0-9][0-9][0-9]_<ident>.cmake

The digits are included in the name to allow sorting priority of
inclusion. The identifier can be used to distinguish who installed the
file.

These files can do any necessary custom version checks.

qtwebengine can install such a file next to the regular file, and
implement the custom logic there.

Due to the glob, this allows other repos (or packagers) to customize
the behavior of the version check of the Qt6 package.

A runtime opt out for this behavior can be enabled by setting the
QT_NO_CONFIG_VERSION_OVERRIDE_FILES variable before finding Qt6.

Packagers can also disable the new behavior at configure time of
qtbase (the code won't be injected) by setting
QT_NO_INJECT_CONFIG_VERSION_OVERRIDE_FILES to ON.
