libphobos: libdruntime doesn't support shadow stack (PR95680)
The first implementation hit a front-end implementation bug where
version conditions are resolved ahead of static if confitions.
The logic for whether to use asm implemented fiber_switchContext or
libc's swapcontext has been moved from GNU_Enable_CET to version CET.
