pkg-infra: allow dumping reverse dependencies of a package
Finding the packages that select another one in a specific configuration
is not very trivial:
- when optional, the dependency is not expressed in Kconfig
- looking at the .mk files is not very nice.
Introduce a way to dump reverse dependencies of packages, i.e. the list
of packages that directly depend on that package. Like for direct
dependencies, we limit the list to the first-order reverse dependencies.
Document it in the main help; use the opportunity to also document
foo-show-depends.
