9ea2f7f4b1 CMake: Fix qml plugin prl files not to have hardcoded paths
The previous fix 754512a64d
did not handle qml plugins, which meant that they would still have
hardcoded paths and see warnings like the one below when generating
the prl files

 CMake Warning (dev) at
 cmake/QtFinishPrlFile.cmake:103 (message):
  Could not determine relative path for library
  qml/QtQml/WorkerScript/libworkerscriptplugin_debug.a
  when generating prl file contents.  An absolute path will be
  embedded, which will cause issues if the Qt installation is
  relocated.

Handle qml plugins as well.

754512a64d CMake: Fix prl files not to contain hard-coded library paths
Make sure to convert absolute paths generated using the
$<TARGET_LINKER_FILE> generator expressions into relative paths.

Because prl files are generated for both modules and plugins, we need
to pass both a list of qt module locations and qt plugin locations
to QtFinishPrl.cmake, and then try to make the absolute path relative
to each passed directory.

A warning assertion is shown if we no relative path could be made,
which will cause an absolute path to be embedded. This should not
happen though.

f4e9981259 CMake: Fix static library link order when using qmake
qmake adds QMAKE_PRL_LIBS values on the link line after the currently
processed library. Because CMake adds resource object files into
QMAKE_PRL_LIBS, they end up on the link line after the library.
This causes issues on Linux with GNU ld and ld.gold, because the
linker discards symbols from the library which are then later referenced
by the object files.

Work around that by placing the path to the library directly into
QMAKE_PRL_LIBS after the resource object files.
This ensures the linker doesn't discard the symbols required by the
resource object files.

This means that each library encountered in qmake's LIBS variable will
be temporarily referenced twice in qmake's project state: once from
LIBS / QMAKE_PRL_TARGET, and once when the QMAKE_PRL_LIBS values are
added. On the link line it will appear only once though, because qmake
does library deduplication during prl file processing, which only keeps
the last occurrence.

2c49f85380 CMake: Fix generated prl and pri files for MSVC
In MSVC static build, if we build Qt with 3rdparty library (e.g. zstd),
cmake will add"zstd" (without "-l" prefix) to Qt6Core.prl. Then we
use this Qt to build a qmake project, compilation will fail due to
missing zstd.obj. Without "-l" prefix, qmake will treat "zstd" as an
object file instead of a library.

Library names in qt_module.pri and qt_lib_*_private.pri are also
missing "-l" prefix.

This is because on most compilers, CMAKE_LINK_LIBRARY_FLAG equals
"-l". But on MSVC, it is an empty string. So we should pass
"-DLINK_LIBRARY_FLAG=-l" for MSVC.

Also add "-L/path/to/library" if the library path is not in default
linker search directories. This will write un-relocatable paths to prl
files only when using 3rdparty libraries to build Qt statically. Usually
it's not a problem.

In addition, CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is also empty on
MSVC. So The third argument of "$<FILTER>" is empty, it is an invalid
generator expression. This means no include dir will be written to
qt_module.pri and qt_lib_*_private.pri on MSVC. So only use "$<FILTER>"
when CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is not empty.

bae96f1792 CMake: Fix generation of prl files for non-qtbase modules
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.

9c0f448f5a CMake: Fix generated content of prl files (again)
Apply the same kind of transformations to the contents of the prl
files as we do for pri files. Mainly, transform system library paths
that are absolute, into link flags to make them relocatable across
systems.

Also change the Qt frameworks to be linked via the -framework flags
instead of via absolute paths.

Implementation notes

Move the common required functions for both QtFinishPrlFile and
QtGenerateLibPri into a common QtGenerateLibHelpers.cmake file.

Make sure it's listed as a dependency for the custom commands.
Also make sure to pass the necessary input values like possible
library prefixes and suffixes, as well as the link flag.

9d55d6b45b CMake: Fix building debug apps with qmake on Windows
Our CMake build system only generated working .prl files for
the Release configuration in debug_and_release.

This caused a linking failure when building a Widgets example that
links against qtmain, specifically

qtmaind.lib(qtmain_win.cpp.obj) : error LNK2019: unresolved external
symbol __imp_CommandLineToArgvW referenced in function WinMain

The symbol is located in shell32.dll, which was not linked in, because
there was no qtmaind.prl file.

The fix to generate per config prl files is a bit complicated, because
add_custom_command does not support generator expressions in OUTPUT
and DEPENDS.

Instead we pre-generate 2 files per config, one with the preliminary
prl file content and another file that contains the final prl file
path (via generator expression).

Then we iterate over all configurations and create custom commands
with well known paths, and the final prl file is created by the script
called by the command.

4ab5432081 CMake: Write object libs of Qt resources to .prl files
Since commit e343affd63 we're creating object libraries for Qt
resources in static libraries. Those must be reflected in the
generated .prl files for static builds of Qt.

In qt_add_resource, we now calculate the install locations of the
object files of rcc-generated C++ files and save them in the target
property QT_RCC_OBJECTS. This property is then passed to
QtFinishPrlFile to write the object file paths to the .prl file.
