Paul Reichert b548cf38b6 feat: enable partial termination proofs about WellFounded.extrinsicFix (#12430) 
This PR provides `WellFounded.partialExtrinsicFix`, which makes it
possible to implement and verify partially terminating functions, safely
building on top of the seemingly less general `extrinsicFix` (which is
now called `totalExtrinsicFix`). A proof of termination is only
necessary in order to formally verify the behavior of
`partialExtrinsicFix`.
