Daniel Paoliello 99c6342b5e [win] Fix EH Cont Guard targets when SEH personality is used (#129612) ...

There were two issues when `/guard:ehcont` is enabled with the SEH
personality on Windows:
1. As @namazso correctly identified, we bail out of
`WinException::endFunction` early for `MSVC_TableSEH` with funclets,
expecting the exception data to be emitted in `endFunclet`, but
`endFunclet` didn't copy the EHCont metadata from the function to the
module.
2. The SEH personality requires that the basic block containing the
`catchpad` is the target, not the `catchret`.

Fixes #64585
