Depending on CMake version suggest usage of either
--debug-find-pkg or CMAKE_FIND_DEBUG_MODE to help troubleshoot
why dependent packages are not found.
To achieve that, append the hint message to the _NOT_FOUND_MESSAGE.
To ensure it works for qt dependencies, and not only tool and 3rd
party dependencies, _qt_internal_find_qt_dependencies
is modified to set variable names infixed by the target name, so the
name is consistent with the other dependency lookup functions.
The check and message are also added when a Qt6 component is not
found.

If find_package(Qt6 REQUIRED COMPONENTS Core) is called, don't
propagate the REQUIRED option to all the dependencies of Core,
regardless if it's a 3rd party library, tool or another Qt package
dependency.
Propagating REQUIRED causes the find_dependency -> find_package call
to exit the calling file immediately when the package is not found,
not giving an opportunity for find_dependency to set the
_NOT_FOUND_MESSAGE variable.
Instead force all find_dependency / find_package calls
to be optional, set the calling _FOUND variable to FALSE if the
dependency is not found, also set the _NOT_FOUND_MESSAGE variable.
Then the find_package call that loaded FooModuleConfig.cmake file
will show that message as the reason for the package not being
found.

Use _qt_internal_find_third_party_dependencies instead.
We rely on the inner find_dependency call to set the
Qt6_NOT_FOUND_MESSAGE message when a dependency is not found.
This implies removing the custom FATAL_ERROR handling
and relying on the parent find_package to display the
Qt6_NOT_FOUND_MESSAGE message.
We also clear Qt6_FIND_COMPONENTS if a dependency is not found.
No need to look for Qt packages if the Qt6 dependency was not met.
This reduces the amount of recursive error messages.

The optional components arguments were not handled before which
caused the recorded package information for static builds to be
incorrect, it only recorded the package name without the component.
Remove REQUIRED_COMPONENTS TODO, there is no such find_package option,
it's already handled by the regular COMPONENTS code path.

Every public dependency of a Qt module results in a find_package call in
the consuming project. But not all public dependencies are mandatory.
For example, vulkan is only needed if the user project actually uses Qt
classes that pull in vulkan headers.
This patch adds the option MARK_OPTIONAL to qt_find_package.
Dependencies that are marked as optional will not produce an error on
find failure.

...in code. The actual number of calls at runtime does not change.
The reason for this stunt is that we want to replace find_dependency
with find_package at runtime for optional dependencies, and this will
reduce the diff size of the next commit.

The find_dependency() macro calls return() on failure, meaning any code
after it will be ignored, thus checking any XXX_FOUND variables after
find_dependency() is pointless.
Fix the places where we use find_dependency() and set the "failed" state
before the call and the "success" state afterwards.

mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.
To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.
We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.
For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).
As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.
