Add internal function to cleanup compiler flags out of the
CMAKE_xxx_FLAGS_xxx variables. Use introduced interface to clear
the '/EHsc' flag for the MSVC compiler family. This adjusts the
CMake behavior to the qmake one.
Change the 'EXCEPTIONS' option handling in helper functions. Add
ability to add enabling and disabling exception flags. Previously
it was only possible to add disabling exception flags.

There is no point in generating cpp files containing Q_IMPORT_PLUGIN()
macro calls for non-executable targets like modules, plugins and object
libraries in a static Qt build.
It causes unnecessary compiling of 10+ files for each of those targets.
In a static Qt build, plugin imports should only be done for executables,
tools and applications.

When a CMake release introduces a new policy that affects most Qt
modules, it may be appropriate to make each module aware of that newer
CMake version and use the NEW policy without raising the minimum CMake
version requirement. To reduce the churn associated with making that
change across all Qt modules individually, this change allows it to be
updated in a central place (qtbase), but in a way that allows a Qt
module to override it in its own .cmake.conf file if required (e.g. to
address the issues identified by policy warnings at a later time). The
policies are modified at the start of the call to
qt_build_repo_begin().
For commands defined by the qtbase module, qtbase needs to be in
control of the policy settings at the point where those commands are
defined. The above mechanism should not affect the policy settings for
these commands, so the various *Config.cmake.in files must not specify
policy ranges in a way that a Qt module's .cmake.conf file could
influence.
Starting with CMake 3.12, policies can be specified as a version range
with the cmake_minimum_required() and cmake_policy() commands. All
policies introduced in CMake versions up to the upper limit of that
range will be set to NEW. The actual version of CMake being used only
has to be at least the lower limit of the specified version range.
This change uses cmake_minimum_required() rather than cmake_policy()
due to the latter not halting further processing upon failure.

Now all shared libraries and executables will get .debug files on
the platforms that support FEATURE_separate_debug_info
With the directory property _qt_skip_separate_debug_info certain
targets can retain the debug symbols in the binary e.g. lupdate with
MinGW 8.1.0 will cause objcopy / strip to fail.

Supports installing linker generated debug info for shared libraries
and executables, as well as compiler generated debug info for static
libraries.
Works with Ninja Multi-Config as well, with the caveat that the files
are installed optionally, aka the install rule will not error out if
a pdb file is not present. This is necessary, because it's not
possible to create per-config install rules properly.

Building a user project in Release configuration against a Qt built with
CMAKE_CONFIGURATION_TYPES=RelWithDebInfo;Debug led to the user project
being linked against the Debug Qt libraries. This is especially painful
with MSVC where debug and release runtimes are incompatible.
We now create *AdditionalTargetInfo.cmake files along the
exported *Targets.cmake files that set the IMPORT_*_<CONFIG> properties
to the values of the release config Qt was built with.
User projects built with an unknown
configuration (CMAKE_BUILD_TYPE=ArbitraryName) will link against a
release Qt. This can be controlled by setting the variable
QT_DEFAULT_IMPORT_CONFIGURATION to, for example, DEBUG in the user
project.

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.
