Rollup merge of #127655 - RalfJung:invalid_type_param_default, r=compiler-errors

Browse source 
turn `invalid_type_param_default` into a `FutureReleaseErrorReportInDeps`

`````@rust-lang/types````` I assume the plan is still to disallow this? It has been a future-compat lint for a long time, seems ripe to go for hard error.

However, turns out that outright removing it right now would lead to [tons of crater regressions](https://github.com/rust-lang/rust/pull/127655#issuecomment-2228285460), so for now this PR just makes this future-compat lint show up in cargo's reports, so people are warned when they use a dependency that is affected by this.

Fixes https://github.com/rust-lang/rust/issues/27336 by removing the feature gate (so there's no way to silence the lint even on nightly)
