CMake makes possible to specify a target in the target_link_library
call even if the target is not declared yet. This adds flexibility to
the target declaration arrangement. For the Qt modules we have to
restrict freedom, because of the .prl files generating. If the Qt
module depends on another Qt module, the dependecy must be declared
before the module finalizing step, otherwise this will cause invalid
records in the module .prl file.
TODO: The dependency order issue could be solved by using conditional
genex's when generating step1 .prl file. But we ask developers to
depend on Qt module targets that have been defined before their usage.

The generated object resource library depends on the Qt::Core library
because uses the functions defined in qresource.cpp. Dummy linking of
the Qt::Core to an object library has an effect only when the object
library is linked directly to the executable as a target. If we link
the object library as INTERFACE library we miss out all the objects
that need to be linked to the executable. This behavior is explained
here:
https://bit.ly/3sFWKvI
Thus, the only option to link the object library objects to the
endpoint executable is to use TARGET_OBJECTS property in genex, as
it's already done. But that means we are losing all profits that
target actually has, especially linking the object library dependencies.
The combination of both of the above methods does the job. The only
thing that looks fragile so far is order. Currently, the order we
use in the target_link_library call applies to the linker command line.
This means the object library objects must always appear before the
object library target.

When building a repository != qtbase, like qtactiveqt, QMAKE_PRL_LIBS
contained entries like Qt6Core and Qt6Widgets, meaning the linker line
would contain exactly these arguments.
When building an activeqt example with qmake, the link then failed with
"LNK1181: cannot open input file 'Qt6Widgets.obj'".
The correct entry would have been $$[QT_INSTALL_LIBS]/Qt6Widgets.obj.
Fix this by determining the full path to the import library in the first
step of the prl generation. This enables QtFinishPrlFile.cmake to
recognize Qt6Widgets as Qt module and generate the right QMAKE_PRL_LIBS
entry.

Before this change, the prl files always assumed that resource object
files are installed into $qt_prefix/lib when doing a prefix build.
That was true for qt_internal_add_resource calls, but not for
qt6_add_qml_module and qt6_target_qml_files.
Change qt_internal_record_rcc_object_files to take a new required
INSTALL_LOCATION argument. The argument takes a path relative
to CMAKE_INSTALL_PREFIX.
Modify __qt_propagate_generated_resource to save the relative path of
the generated resource source file, which will be used in the
computation of the final resource object file location.
This is needed because the Qml resource functions place the source
files in a different directory layout, e.g. .rcc vs .qmlcache
Modify qt_generate_prl_file to prepend $$[QT_INSTALL_PREFIX]/
instead of $$[QT_INSTALL_LIBS]/ for the resource install paths.
A follow up patch is done in qtdeclarative to pass the new
INSTALL_LOCATION argument from the Qml CMake functions.

The CMake build of Qt intends to improve the developer experience in
regards to static Qt builds and Qt resource files. Specifically with a
CMake build of Qt, Qt developers don't have to manually call
Q_INIT_RESOURCE anymore.
For details see the following commits
e343affd63e817ac3d684ab5432081
The last commit's implementation is incomplete though.
To ensure successful linking, each target's prl file should contain
not only the resource object files that are assigned to the target,
but also all resource object files of the target's dependencies.
To achieve that, qt_collect_libs will now recursively collect all
resource object files assigned to the QT_RCC_OBJECTS property of each
dependency.
Note this implementation is still incomplete. We do not export rcc
object file information in the CMake Targets files.
That means that when configuring qtdeclarative in a
non-top-level build, the generated Qml prl file will not
contain references to Core's mimetypes resource object file, etc.
So with the current change, only the object files that are part of the
current CMake configuration build are tracked.
Exporting the resource object files locations proves in a format
usable for prl files proves to be difficult (due to CMake not
supporting exporting genexes in random properties) and will have to be
addressed in a separate change.

Refactor the function in preparation of processing rcc object files.
Introduce 2 new functions to get and set values in the memoization
dictionary used by qt_internal_walk_libs.
Modify qt_internal_add_target_aliases to assign the alias names it
creates as properties on the target.
Extract these aliases when available to assign memoized values not
only for the initial library name, but also for its aliases.
When recursively calling qt_internal_walk_libs, make sure to provide a
unique out_var name based on the outer target name, and not just
lib_libs. Otherwise the out_var values would be polluted from
previous recursion runs.
Make sure to check for -NOTFOUND in if() checks so that we reuse
memoized values that are the empty string.

Previously we determined if a library represented by an absolute path
is a Qt module by checking if it's located in the build dir of the
current repo.
That is not sufficient for non-qtbase prefix builds, where
a Qt module might link against both a module in the current
build dir and in the prefix dir.
Detect such cases, and rewrite the absolute paths to relocatable paths
(either framework flags or paths starting with $$[QT_INSTALL_LIBS].
This should fix building examples with qmake that use QtQuick.

Add an abstraction over Qt::WinMain (aka qtmain.lib) and
iOS's runtime linker entry point (_qt_main_wrapper).
The Core target will now link against the Startup target on all
platforms, instead of just WinMain on Windows.
The creation and linkage interface definition of the Startup target
is done at find_package(Qt6Core) time via the private call of
_qt_internal_setup_startup_target().
This will add automatic linkage of WinMain to executables marked with
the WIN32_EXECUTABLE property on Windows.
As well as the addition of the '-Wl,-e,_qt_main_wrapper' linker flag
when linking iOS executables.
Qt users can opt out of this behavior by either setting the
QT_NO_LINK_QTMAIN property or variable. This is in line with
Qt 5 behavior.

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.
