Automated rollback of commit 2a28909.

*** Reason for rollback ***

We're no longer going with this approach.

*** Original change description ***

Add RunfilesLibraryInfo

The new provider marks runfiles libraries as such and will be used by
both Bazel itself and language rules to emit additional information
required for executable targets to find their runfiles in the presence
of repository mappings.

Work towards bazelbuild#16124

Closes bazelbuild#16125.
