Rollup merge of #111252 - matthewjasper:min-spec-improvements, r=compiler-errors

Min specialization improvements

- Don't allow specialization impls with no items, such implementations are probably not correct and only occur as mistakes in the compiler and standard library
- Fix a missing normalization call
- Adds spans for lifetime errors from overly general specializations

Closes #79457
Closes #109815
