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.

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.

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.

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.

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.

The module name in the .pri file is not versioned when it's a bundle.
