JIT: Fix OSR local detection for implicit byref promotion (#67678)

In #67247 I revised how the JIT determines if a local requires special
handling for OSR, but for implicit byrefs we may move locals for promoted
fields back and forth between parents and this messes with the new logic.
The fix is to reset the `lvIsOSRLocal` bit explicitly when creating the
fields for an implicit byref promotion.

Also added a bit of sanity checking to `lvaIsOSRLocal`.

Fixes #67488.
