CMake: Allow usage of QtStandaloneTestTemplateProject as package component

Currently in order to compile a Qt6 test standalone one needs to use
the qt-cmake-standalone-test script which will load the
Qt6BuildInternals/QtStandaloneTestTemplateProject/CMakeLists.txt project
with the current test source directory to create a complete CMake project.

This commit will allow a test to have these lines at top:

cmake_minimum_required(VERSION 3.16)

if (NOT QT_BUILD_STANDALONE_TESTS AND NOT QT_BUILDING_QT)
    project(a_qt_test LANGUAGES C CXX ASM)
    find_package(Qt6BuildInternals COMPONENTS STANDALONE_TEST)
endif()

and be standalone and work with any IDE capable of loading CMake projects.

Fixes: QTCREATORBUG-25389
Pick-to: 6.1
