Rollup merge of #99011 - oli-obk:UnsoundCell, r=eddyb
`UnsafeCell` blocks niches inside its nested type from being available outside fixes #87341 This implements the plan by `@eddyb` in https://github.com/rust-lang/rust/issues/87341#issuecomment-886083646 Somewhat related PR (not strictly necessary, but that cleanup made this PR simpler): #94527
