Now that we run tests for static Qt builds in the CI, it makes sense
to restore the CMake build tests that check that static plugin
importing works correctly.
Resurrect the previously commented out test_import_plugins project and
port the mockplugins qmake projects to CMake.
mockplugins is a CMake project that uses the internal Qt CMake API to
build and install some Qt modules and plugins.
test_import_plugins depends on that test (via a CMake fixture) to
build public projects that use those plugins.
The installation of the mockplugins modules pollutes the Qt install
prefix, but in the CI that only happens on the test VM, which means
the release packages are not affected.
Locally on a developer machine the Qt install path will be polluted,
but it's not that much of a big deal. We could try and address that in
a future change by using the QT_ADDITIONAL_PACKAGES_PREFIX_PATH
functionality added for Conan to allow the installation of Qt packages
into a non-standard prefix.

This commit adds transitive dependencies to the plugins, so that a
sane set of default plugins get auto-imported when linking against a
module. It also provides a new function, qt5_import_plugins(), which
allows you to override the set of plugins that get imported. The decision
of whether or not to import a specific plugin is based on several custom
target properties and a very clever generator expression.
Note that this change only imports plugins on static Qt builds. It
does nothing on shared Qt builds, as the shared libraries already have
their own plugin import mechanism.
