[WinEH] Delete the old landingpad implementation of Windows EH

The new implementation works at least as well as the old implementation
did.

Also delete the associated preparation tests. They don't exercise
interesting corner cases of the new implementation. All the codegen
tests of the EH tables have already been ported.
