BUG: Fix LOCATION property for Mac AppBundles

Previously cmTarget::GetLocation and cmTarget::GetFullPath would return
for Mac AppBundles the top-level bundle directory but without the .app
extension.  We worked around this at the call sites.  This fixes the
methods and removes the work-arounds.  See issue #8406.
