Fix name parameter templating in include_role module (#36372)

An IncludedFile() object built using the original_task will have
its _task bound to the original_task. The iterative reassignment of
original_task._role_name during with_item loops leaves all returned
included_files with the same ._task._role_name (the final name from
the with_items list). This commit builds IncludedFile() objects
from an original_task.copy() to avoid the problematic binding.
