bors c067287049 Auto merge of #97024 - lcnr:simplify_type-sus, r=<try>
`simplify_type` improvements and cursed docs

the existing `TreatParams` enum pretty much mixes everything up. Not sure why this looked right to me in #94057

This also includes two changes which impact perf:
- `ty::Projection` with inference vars shouldn't be treated as a rigid type, even if fully normalized
- `ty::Placeholder` only unifies with itself, so actually return `Some` for them
