[WinEH] Fix endpad coloring/numbering

Summary:
When a cleanup's cleanupendpad or cleanupret targets a catchendpad, stop
trying to propagate the cleanup's parent's color to the catchendpad, since
what's needed is the cleanup's grandparent's color and the catchendpad
will get that color from the catchpad linkage already.  We already had
this exclusion for invokes, but were missing it for
cleanupendpad/cleanupret.

Also add a missing line that tags cleanupendpads' states in the
EHPadStateMap, without with lowering invokes that target cleanupendpads
which unwind to other handlers (and so don't have the -1 state) will fail.

This fixes the reduced IR repro in PR25163.
