Fix JIT debugger notification location (#53590)

* Fix JIT debugger notification location

My recent change to enable jitting into a scratch buffer has broken
debugging due to the notification to debugger being sent too early. This
change moves the notification after the call to WriteCode and also
removes the CallCompileMethodWithSEHWrapper completely, since its only
purpose was to call the notification in PAL_FINALLY and only when the
JITting succeeded.

* Fix #endif comment
