Rollup merge of rust-lang#133142 - RalfJung:naming-is-hard, r=compiler-errors

rename rustc_const_stable_intrinsic -> rustc_intrinsic_const_stable_indirect

In rust-lang#120370 this name caused confusion as the author thought the intrinsic was stable. So let's try a different name...

If we can land this before the beta cutoff we can avoid needing `cfg(bootstrap)` for this. ;)
