Download cached source directories in the runfiles of top-level targets (#31473)

### Description

The files below a source directory of a repo that has been retrieved from the remote repo contents cache are only downloaded when the directory is requested from the prefetcher. For the runfiles of a top-level target, only artifacts with remote metadata were requested, which a source directory doesn't have.

Source directories in external repos are now requested as well if they are selected for download.

### Motivation

With a source directory of a cached repo in the runfiles of a binary, `bazel run` ran the binary without the directory in its runfiles tree.

Work towards #31456

### Build API Changes

No

### Release Notes

RELNOTES: None

Closes #31473
