Rollup merge of #35663 - CryZe:no-stdlib, r=Manishearth
Improve `No stdlib` and related Documentation This renames all lang item function names to the ones used in `libstd` and `libpanic_unwind`. It also explains the `eh_unwind_resume` lang item in the `libcore` documentation, where it was missing. A third function is also needed on certain compilation targets, so this was also added to the `No stdlib` documentation.
