create-spdx-{2.2,3.0}: fix do_create_spdx dependency while spdx include sources

Call function ${@create_spdx_source_deps(d)} or ${create_spdx_source_deps(d)}
along with addtask not working, use task do_create_spdx flag 'depends'
to instead

Move function create_spdx_source_deps to spdx-common.bbclass for both of
create-spdx-2.2.bbclass and create-spdx-3.0.bbclass
