Introduce a bunch of helper functions to manipulate compiler
flags and linker flags for the
CMAKE_<LANG>_FLAGS_<CONFIG>
and
CMAKE_<LINK_TYPE>_LINKER_FLAGS_<CONFIG>
CMake variables.
These variables can be assigned and modified either in the cache
or for a specific subdirectory scope, which will apply the flags
only to targets in that scope.
Add qt_internal_add_optimize_full_flags() function which mimics
qmake's CONFIG += optimize_full behavior.
Calling it will force usage of the '-O3' optimization flag on supported
platforms (falling back '-O2' where not supported).
Use the function for the Core and Gui subdirectories, to enable full
optimization for the respective Qt modules as it is done in the qmake
projects.
To ensure that the global qmake-like compiler flags are assigned
eveywhere,
qt_internal_set_up_config_optimizations_like_in_qmake() needs
to be called after Qt global features like optimize_size and
optimize_full are available.
This means that qtbase and its standalone tests need some special
handling in regards to when to call that function.

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.

This is needed for qtwayland, where QtWaylandCompositor package should
call find_package(QtWaylandScanner) in the 'Tools' section of the
ModuleDependencies.cmake file, rather than the regular 'Qt' section.
This takes care of handling host path prefixes, to ensure that a host
package is found even when tools have also been cross-compiled via the
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING option.

qt_record_extra_package_dependency is called by qtwayland to register a
dependency between the qtwaylandscanner tool and the waylandscanner
tool.
When cross-compiling the tools in a Yocto environment, the adjusted
target name was not taken into account.

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.
