<summary>Changes</summary>

This patch is part of a series of splitting the work from #<!-- -->169964 into 
smaller changes (see review linked below).

As part of this work, the regular and by-name dependency scanning APIs need to 
be extended to allow the VFS to be initialized via the `initVFS-` helpers 
before invoking the scanning API, with the resulting overlay filesystem passed 
into the worker instead.

To make the newly added API changes consistent, this patch updates both helpers 
to return an `OverlayFileSystem`.
