b6c5e06676 CMake: Handle OPTIONAL_COMPONENTS in qt_find_package
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.

3685483c4b CMake: Add facility to mark package dependencies as optional
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.

a3cb002511 CMake: Reduce the number of find_dependency calls
...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.

58c1c6ee5c CMake: Fix usage of find_dependency()
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.

92ee9bd6b8 CMake: Properly handle CONFIG += thread aka Threads::Threads
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.
