029e118a4e CMake: Unify usage of pkg_check_modules
According to the CMake documentation, IMPORTED_TARGET should be
specified before the moduleSpec, and after QUIET.

Additionally, double-quote the moduleSpec everywhere, since before, it
was only quoted in some cases.

While this is not required for pkg_check_modules to work, it unifies the
coding style.

af56a6f0cb CMake: Don't force CONFIG mode when looking for system PCRE2
This allows picking up 3rd party Find modules. One use case is
Conan-generated Find modules.

Also add TODO in case we ever need to handle finding the upstream
target name rather than the Hunter chosen one.

bfd9e195a3 CMake: Fix lookup of system PCRE2 version
The version option needs to be specified before the COMPONENTS
option, otherwise it is treated as another component.

This causes failures when a Conan provided FindPCRE2.cmake script is
picked up, which actually does validation of component names based
on the component information stored in the conanfile.py recipe.

Move the version value to be before COMPONENTS.

1007aac63a Fix check for pcre2 using cmake
When PCRE2 is compiled using cmake, a pcre2 cmake file is installed
and Qt fails to configure because components isn't specified for
find_package.
In recent PCRE2 releases components needs to be specified for
find_package.

3c52f8af9d CMake: pro2cmake: Specify library versions for 3rd party libraries
If certain 3rd party libraries have a version that's not suitable for
Qt, the configure summary should say so, rather than use them and fail
at build time.

With the current situation, we have to duplicate the version
information from the configure.json files in helper.py, by assigning
the version number as an extra find_package variable.

Rerunning configurejson2cmake then embeds this version info into the
qt_find_package calls in configure.cmake.

Some of the Find modules are rewritten to take the  specified version
into account when looking for the libraries.
This involves moving around the code for creating a target, after
calling find_package_handle_standard_args() so we know if a good
enough version was found.

26059d1b9b CMake: Allow building bundled 3rd party libraries in qtbase
A few things are needed to accomplish that:

- the python scripts do not ignore certain system_foo features anymore
  (it is a hardcoded list for now just to be safe)

- configurejson2cmake now outputs
  qt_find_package(WrapSystemFoo) calls for bundled libraries
  (see below)

- the harfbuzz .pro file is modified to accommodate pro2cmake
  not being able to correctly parse some conditional scopes

- the freetype .pro file is modified to make sure linking of the
  library succeeds without duplicate symbol errors, which qmake
  doesn't encounter due to magical exclusion of cpp files that are
  included in other cpp files (presumably for include moc_foo.cpp
  support)

- feature evaluation for Core, Gui, Network now happens in the
  qtbase/src directory, so that bundled libraries can be conditionally
  built

- for each bundled library there are now two FindWrap scripts:
  - FindWrapSystemFoo which finds an installed library in the system
  - FindWrapFoo which either uses the system installed library or
    the built bundled one depending on a condition

- projects that intend to use bundled libraries need to link against
  WrapFoo::WrapFoo instead of WrapSystemFoo::WrapSystemFoo targets
  (this is handled by pro2cmake).
  Unfortunately manually added qt_find_package(WrapFoo) calls might
  still be needed as is the case for WrapFreetype and others.

- a new cmake/QtFindWrapHelper.cmake file is added that provides
  a macro to simplify creation of WrapFoo targets that link against
  a bundled or system library. The implementation is fairly ugly
  due to CMake macro constraints, but it was deemed better than
  copy-pasting a bunch of almost identical code across all
  FindWrapFoo.cmake files.

- a qtzlib header-only module is now created when using bundled
  zlib, to provide public syncqt created headers for consumers
  that need them. These are projects that have
  'QT_PRIVATE += zlib-private' in their .pro files
  (e.g. qtimageformats, qtlocation, qt3d, etc.)
  This is unfortunately needed due to QtNetwork using zlib
  types in its private C++ API.

The change includes support for building the following bundled
libraries:
- zlib
- libpng
- libjpeg
- Freetype
- Harfbuzz-ng
- PCRE2

The following 3rd party libraries are still using an old
implementation within the CMake build system, and should be migrated
to the new one in the near future:
- double-conversion
- Old harfbuzz

The are a few libraries that are not yet ported:
- system-sqlite
- systemxcb
- maybe others

Among other things, this change allows building qtbase on Windows
without requiring vcpkg.
