Brad King 8dfc725cdb PathResolver: Add mode to collapse paths naively and look up on-disk case ...

In CMake 3.31 and below, `CollapseFullPath` did this on Windows.  KWSys
has since stopped looking up the on-disk case in `CollapseFullPath` to
avoid disk access when most callers only need an in-memory operation.
We currently call `GetActualCaseForPath` explicitly when needed.

Add a mode to `cm::PathResolver` to combine these operations and cache
disk access behind the `System::ReadName` callback.  We will use this to
restore the way CMake 3.31 and below normalized input paths on Windows.
