Subject: [PATCH] CMake: Add test for configuring a standalone test

A standalone test is one that uses
 find_package(Qt6BuildInternals REQUIRED COMPONENTS STANDALONE_TEST)
in its project code.

To ensure we don't accidentally regress this feature, test it as a
cmake test.
Also run test, this somewhat covers testing qt_internal_add_test.

Pick-to: 6.6 6.5
