An approach of test batching (joining multiple tests into a single binary) has been taken, due to long linking times/binary size on certain platforms, including WASM. This change adds a new feature 'batch_test_support' in Qt testlib. Based on the value of the feature, test batching may become enabled with the -batch-tests switch. Batching works for every target added via qt_internal_add_test. When first such target is being processed, a new combined target for all of the future test sources is created under the name of 'test_batch'. CMake attempts to merge the parameters of each of the tests, and some basic checks are run for parameter differences that are impossible to reconcile. On the C++ level, convenience macros instantiating the tests are redefined when batch_tests is on. The new, changed behavior triggered by the changes in the macros registers the tests in a central test registry, where they are available for execution based solely on their test name. The test name is interoperable with the names CMake is aware of, so CTest is able to run the tests one by one in the combined binary.
