x86/retpoline: Document some thunk handling aspects
After a lot of experimenting (see thread Link points to) document for
now the issues and requirements for future improvements to the thunk
handling and potential issuing of a diagnostic when the default thunk
hasn't been patched out.
This documentation is only temporary and that close before the merge
window it is only a placeholder for those future improvements.
