Update DependentProjectsFinder to only return projects supporting compilations

AddNonSubmissionDependentProjectsAsync is designed to return projects
that depend on a given symbol. It indirectly calls HasReferenceTo
which in the metadata paths will only return projects that have
Compilation support. Thus, it seems safe to exclude the projects
entirely.

Fixes dotnet/roslyn#25655.
