Improve double call protection of qt_internal_generate_tool_command_wrapper

Browse Source 
file(GENERATE) might fail if an unrelated configuration error happens,
and yet QT_TOOL_COMMAND_WRAPPER_PATH would already be set. Set the
cache variable only if generating was successful and replace the
QT_TOOL_COMMAND_WRAPPER_PATH valiable check with GLOBAL property to
protect the function from double call.

For CMake versions higher than or equal to 3.18 replace 'file(GENERATE'
call with 'file(CONFIGURE' to generate the wrapper at configure time
with the use of a plain semicolon character.

Pick-to: 6.2
Fixes: QTBUG-96870
