Add handling of -binary flag in qt6_add_resources for generated
resource file variant.
If -binary argument is provided in OPTIONS section of
qt6_add_resources function, it will be passed to rcc as argument.
File path to output .rcc could be additionally specified by
DESTINATION argument. Extra target generated_<resource_filename>
will be added to project's 'all' set.
Implement tests for new functionality.
