Allow Abort terminators in a const-context
...
These appear along the cleanup path inside functions with
`#[unwind(aborts)]`. We don't const-check the cleanup path anyways,
since const-eval already has "abort-on-panic" semantics and there's
often drops that would otherwise be forbidden, so the check wasn't
really preventing anything anyways.

This helper function was meant to reduce code duplication between
const-checking pre- and post-drop-elaboration. Most of the functionality
is only relevant for the pre-drop-elaboration pass.

Suggest `const_fn_transmute`, not `const_fn`
More fallout from #76850 in the vein of #77134 . The fix is the same. I looked through the structured errors file and didn't see any more of this kind of diagnostics bug.
