  [WinEH] Track changes in WinEHPrepare pass (#134121)

Before this change, the pass would always claim to have changed IR if
there is a scope-based personality function. We add some plumbing to
track if there was an actual change.

This should be NFC, except that we might now preserve more analysis
passes.
