Rewrite part of the dependency scanner into a class so it is easier to keep track of the global states and avoid redundent work. This allows folding the pruning unused VFS job into the same loop and reduce a lot of repeated dependency cache updates.

In the refactoring change swiftlang#76700, it accidentally introduced a behavior change that causes the generated PCM command-line to have useful VFSOverlay files getting dropped. Clang module command-line and its unused VFS pruning should be done by the clang dependency scanner already so there is no need to touch that in the swift scanner. Since the original logics is not used to handle clang module commands, it will actually dropped the useful vfs overlay that is needed when none of the dependencies uses it. Fix the regression by restoring the old behavior and ignoring clang modules when pruning VFS overlay. rdar://139233781

…odules When planning for a swift source module, it should not get build commands for its module dependencies. Those dependencies should be planned and added by swift-driver. This is another regression from swiftlang#76700 that causes unnecessary increase of build command-line size. rdar://141843125
