Previously one had to add the Qt bin dir and libclang.dll dir to PATH manually to ensure shiboken successfully runs when building Qt for Python using CMake without setup.py. This should not be necessary though, because the build system knows where Qt is (usually via the --qtpaths option) and where libclang is (via LLVM_INSTALL_DIR and friends). Introduce a CMake function that generates a batch shell script wrapper for a given tool. The wrapper will have PATH set to the Qt bin dir and libclang dir. Generate such a wrapper for shiboken and use it everywhere we call shiboken to generate bindings. The wrapper is only created on Windows. All mentions of Shiboken6::shiboken in custom commands now need to be wrapped in $<TARGET_FILE> because automatic target path conversion only happens if the target appears as the first argument to a custom command, and that is not the case anymore with the wrapper script being at the front. As a drive-by, the indentation of custom commands is now adjusted for easier readability and to conform with the indentation used in the Qt build system.
