Rollup merge of #57564 - varkor:update-const_fn-tracking-issue, r=Centril

Update the const fn tracking issue to the new metabug

The new `const fn` tracking issue is #57563. We don't want to point to a closed issue in the diagnostics (or FIXMEs), so these have been updated (from the old issue, #24111).
