util/dasharo/tag-with-changelog: list edk2 and submodules commits

Other payloads aren't supported.

Both submodules and edk2 commits are nested one level deeper that the
main log. This is a compromise between enough information (previously
just the number of commit added in a submodule was printed) and clear
grouping between categories.

Changelog for edk2 is limited in history, it starts with the first
commit pointed to by common Kconfig default. For releases made before
this commit, a warning about a possibly incomplete edk2 changelog
will be shown in the comment just above the changelog. The changelog
will be complete only if older tag is made after this commit, in most
cases this will be two releases (or release candidates) from now, for
each platform separately.
